First off, let me say that this was a very ambitious movie that I'm happy was made. It was fairly enjoyable. I did enjoy the questions and thoughts sparked by the relativity concepts expressed (time dilation). Alas, at the end of the movie I was wishing I could send a message back through time to go see John Wick instead and wait for Interstellar on DVD.
My thoughts on the movie.
1) ROBOTS
Like many on this board, I thought the robots were fantastic and possibly stole the movie though . . . like some . . . I didn't entirely buy into how they were able to walk. Still, I went with it.
2) THE BLIGHT AND SUFFOCATION
I thought that someone in the movie said that the earth's air was becoming too nitrogen rich because and eventually humans would suffocate. The blight that was destroying certain food crops lived off of nitrogen. Well . . . if they lived off of nitrogen then wouldn't they be REMOVING nitrogen from the atmosphere instead of creating more? Maybe I misheard that but it didn't make sense. And on the drive to the secret NASA station there seemed to be a lot of plant life left creating oxygen so where was the nitrogen coming from? Maybe them meant to say the blight was "creating nitrogen" though that would be killing a lot of life on earth, not just humans. It doesn't seem likely that nature would create something that kills off all other life and then can't even sustain itself (a planet killing plague that destroys itself too!).
3) SPACE TRAVEL
Humans couldn't travel between star systems here but if you go to another galaxy you can travel to 6 or more DIFFERENT solar systems? Sure, one with a giant black hole (hey, a habitable world revolving around a black hole? Sound promising, lets move there!!!) There were three around the black hole which I assume was close to the other end of the wormhole . . . but how close were the other solar systems that NASA expeditions could get there in a few years rather than decades or hundreds of years? Apparently solar systems are a lot closer together in this new galaxy or the wormhole can take you wherever you want to go depending on your trajectory of entry (different destination wormhole?).
4) WAVE PLANET
I thought the time dilation effects of the first planet was very thought provoking, I loved it. However, I am pretty sure if you are close enough to a black hole to experience something like that you would be crushed to dust. Even if you got to the planet, you couldn't get off (the black hole's gravity). Plus fellas . . . that planet is probably very close to getting sucked into a black hole!!! How could they think life could develop or exist on a planet that's temperature is constantly varying because its orbit is always changing (duhh . . . orbital decay towards a black hole)? Not to mention, what caused those giant tidal waves? Is gravity just really strong at one point and as the planet rotates you run into that big tidal wave? The planet must be spinning pretty fast because those waves seemed to move awfully damn quickly. Plus gravity doesn't really work like that. The best part was the idea that they had landed just minutes after the original mission because of the time dilation effect. Though did nobody notice that the readings sent from that planet occured decades after the others were received? And she really made some fast determinations and sent them (thought decades would have passed in our time) since the time between those first two waves was only like . . . what . . . 25-30 minutes? Just given the location of the planet and inherent problems with it . . . would that really be your 1st choice of a planet to investigate?
5) NO MILITARIES
Cooper or someone stated that because of the mass starvation (I understood that a majority of the population had starved after Lithgow mentioned there were once 6 billion people on the planet and acted like that was an amazing number) there was no need for armies anymore. So am I supposed to believe that in a world where food is a resource that can mean the survival or extermination of entire nations or areas of the globe that no one attempted to take over a neighbors resource by force? And that time of war (when NASA was asked to drop bombs on starving people) didn't damage the ecology or atmosphere at all? If it did, at least it didn't effect small town Iowa or Kansas (or wherever they were). Plus the NY Yankees sometimes visited to play there!!! I assume the dust storms were caused by drought and blight (destroying vegetation) rather than the lingering effects of a war. But I guess people are all peaceful now even though food is still a problem (Hell, Okra just went out the window last year) so a military isn't a problem.
6) THE UAV
What was the point of the UAV? My son asked me this after the movie. Sure, it was a cool scene and interesting but did it have anything to do with the actual plot? Was it explained? Did the UAV just go off flying on its own for decades without an owner simply because it was solar powered until Cooper caught it? Am I mistaken or was that the gist of it? Was it meant to show how advanced AI had become at that time in place (since I definetely expected to see more electric cars and fewer cars that were built in the early 2000s. Remember, Lithgow said that when he was a boy the Yankees had real ball players while Coop said that when he was younger they didn't have time to play baseball (or something to that extent). This suggests a lot of time has passed since well . . . when that truck he drove was first developed. But I digress, was the UAV scene at all necessary to a movie that did seem a bit too long?
7) SPACE STATION
Weren't they building the space station underground at NASA and actually working within what they were going to take into space (after they solved the Gravity equation or something)? Is it me or did there seem to be a lot concrete in that building (station). Based on the strengths and weaknesses of concrete this would seem to be a terrible material to use to build any part of a space station out of unless it was entirely on the inside surrounded by metal. Then again, maybe I misunderstood that part of the dialogue and the two weren't one and the same.
8) PROFESSOR MANN
Yeah, I get it. He went crazy and thus he isn't expected to be logical. I assume he disabled his robot because he wanted to broadcast (after a couple of years) that his planet was awesome and great for life but the robot wouldn't let him broadcast false information. Or maybe KIP just pissed him off somehow. But either way, Mann decided to configure Kip to explode if his memory was accessed by another human. Hmmm . . . so what if after he went to sleep the first people arrived tried to access Kip before waking Mann? I guess he goes bye-bye too. Or, how ironic, if as he's waking up from cryosleep he hears another astronaut in the background saying, "Okay, I'm accessing KIP's memory now!" Kaaah Bloooey! Because the fact is, he must have set the self destruct when KIP still had a functioning power source and KIP wouldn't have a new power source until AFTER new astronauts had arrived. This is a minor complaint but for a man now obsessed with living, setting an active booby trap in your life habitat seems a bit of a risky proposition when you could still be unconcious when its activated.
9) COOP REVIVED IN THE FUTURE
So Cooper exits the black hole and is rescued by the humans who went to space. Now he's recuperating to find out that mankind is living out in the stars in giant space stations (at least two since his daughter was in another one). And they were near Saturn (or at least their patrols are). He enters his daughter's room. The rest of her family is there (which is his family too) but don't seem to care that superhero grandpa is alive and returned from another galaxy despite her grandma's Murph's everwhelming obsession with him. He might as well have been an orderly the way they reacted to him. I found that odd. Then she tells him to go back and find Brand who is all out there by herself starting up a new human colony. Did Murph mean that she had "started up" a colony . . . like 50-60 years ago? Because outside of the Wave planet time is pretty consistent between the two galaxies. Coop was 120ish now and his daughter 100. So she figured out the Gravity equation around Coops age when he left in her 40s (give or take a decade) and Coop shows up when mankind is already out in space. Well the time that passed between his entering the black hole in its galaxy and in ours would be pretty much the same. So either Brand landed on the planet and set up for raising the future of humanity or she said "F**k it" and went into hybernation. Either way, how the hell would Murph know? So humans are out into space in giant space stations, patrolling Saturns moons but they NEVER bothered to go back through the wormhole to check on Brand or the other astronauts? ("Ehh, f**k em! We have the gravity formula now anyways.) Did she just get this knowledge from future humans and only she knows? Is Coop not only supposed to get to Brand in a patrol craft (that you can steal pretty damn easily I might add) but also travel back in time while doing so he can get there when she's alone (because she's she's in her 70s with a bunch of other humans she created with the Plan B embryos or she scrapped the mission and decided to just sleep for as long as her chamber lasted which would contradict what Murph somehow knew). And how does Coop know that Brand's boyfriend isn't still alive and just had a radio malfunction? Talk about being a 3rd wheel. Stuck on a planet with the girl you like and her . . . *cough, cough* . . . boyfriend. Seriously, WTF???
10) ALIENS (SUPERHUMANS FROM THE FUTURE)
Here's the big problem. If humanity survived the crisis on earth, why the hell are they going back in time to help humanity survive? Isn't the real danger that you accidentally alter the timeline to something that DOES end up with the extinction of the human race? If you do nothing, its cool. If you try to help them you might never exist. Doing nothing sounds like a win-win. Doing something seems like a potential win-lose so . . . why?
Plus, with all that advanced knowledge and technology they sure left a lot to chance. If you want humanity to spread to other galaxies when they are on their deathbed why not find a nice planet and set the exit to the wormhole close enough that it's pretty obvious where you want your ancestors to go. Why all the BS? I guess when you are almost super advanced and intelligent you forget how to communicate with your earlier, stupid ancestors. And really, without the robots we humans are f**ked. TARS is really the one who solved the Gravity equation. Coop just morse coded it into Murph's watch (somehow). Superadvanced human race who's master plan doesn't work unless a human eventually gets sucked into a black hole . . . with a robot. Whew, talk about having everything break your way!!!
And lets disregard the time travel quandry that the human race doesn't survive without the help of future humans who don't exist unless humans survive who don't survive without the help of future humans who don't exist unless humans survive and so on, and so on, and so on . . .
I had a great time thinking about all the plot holes of the movie but that is not why I only gave this movie a B-/C+. It just seemed to drag a bit to much at times and the flashbacks of the space climax with Murph on earth just didn't match up well. I wasn't even sure if those things were supposed to be happening at the same time. It worked better in Inception than here.
