1. Wouldn’t it have been way better for Professor Brand (Michael  Caine) to just send the super-robots? Sure, we’re told bots can’t  improvise. But they also don’t freak out about being stranded, want to  check out planets where their lovers are stationed, and make decisions  based on getting home in time for their daughter’s birthday. Plus,  having people on the ship requires more oxygen, food, water, fuel and  ways to watch 
Survivor videos from home that rip your heart out.
 2. There’s a reference to land wars having come and gone, but still:  Wouldn’t the starving hoards of desperate humanity kill the farmers and  take what was left? Are we really supposed to believe, in a society  where the military has collapsed, they’d just slink away in their dusty  cars to die? Or are the very least, wouldn’t they raid the corn fields  for all the food? Clearly Nolan has never worked in a restaurant — you  put suburbanites on a 40-minute wait for a booth and by the end of it  they’re ready to claw your eyes out. Even the nice hobbits stole from  Farmer Maggot.
 3. Cooper (Matthew McConaughey) gives his daughter Murph (Mackenzie Foy) a soothing explanation of the origin of Murphy’s Law. This isn’t actually true. 
The term means  pretty much what you thought it meant — if anything can go wrong, it  will (like, for instance, your dad taking off for 80 years, leaving you  behind to eat corn with dust sauce). Speaking of: Cooper shows up  randomly at NASA and suddenly he’s piloting the craft? If he’s so ideal  for this incredibly important Earth-saving mission that’s just about to  happen, and even knows the professor, and is just a day’s drive away,  you would think they might have already known he was working the farm  down the street and reached out to him. Did NASA not have a pilot before  he showed up?
 4. Why are the watery vacuum-seal sleep chamber containers so filthy?  Did Murph leave the window open on the space station during a dust  storm? And did Nolan lift that the paper-and-pencil explanation of  wormholes from 
Event Horizon?
 5. Was this the first movie where aliens played a major role, but we  did not see any aliens? Or wait: There were no actual aliens, and it was  just humanity in the future, right? Either way: Cooper is definitely  revealed to be Space Ghost, supplying his daughter (and his younger  self) with information. How is that not a cap-P Paradox?
 6. So you can receive depressing videos from your loved ones about  how you’re a crappy father on the other side of the galaxy and through a  wormhole, but nobody could send Earth back any detailed information  about the habitability of the prospective planets that mankind is  depending on? And would Murph really continue being so angry with her  dad for participating in the save-humanity project when she’s spending  her life devoted to the exact the same project?
 7. How is Romilly (David Gyasi), who waited  23 years for Cooper and Brand (Anne Hathaway) to get back to the ship,  not totally insane? He took a couple sleep breaks but clearly spent well  over a decade alone. Wouldn’t he be collecting jars of his urine and  wearing tissue boxes on his feet by now instead of looking like a dad  who’s mildly perturbed at his kids for staying out too late? Why not,  after finishing his complex math homework, didn’t he just stay in the  sleep chamber and trust Cooper and Brand to eventually wake him up  rather than remaining for years roaming around the ship looking out the  window, waiting for the headlights of their returning shuttle? Romilly  is the most tragic character in this movie. Murph lives a long life and  has a ton of distractions to keep her occupied — such as her grouchy  brother, Michael Caine, a surprise Topher Grace and a meaningful job —  yet we’re supposed to feel really sorry for her. But Romilly waits  around for 23 years in space, bored out of his mind, somehow manages to  keep his wits together, only to get blown up by sad Matt Damon. From  Romilly’s perspective, this movie was a total tragedy.
 8. Speaking of which, let’s talk for a minute about Damon’s character  Dr. Mann (Get it? Man’s greatest enemy is Mann — the Waterwold planet  was a man vs. nature challenge, then the Hoth planet was a man vs. Mann  challenge). Did anybody else get the impression if Mann just would have  opened with, “Sorry about the pings, I was crazy lonely and going nuts,”  the other astronauts would have thought he was super unprofessional,  but still let him tag along to the next planet? And how come, with a few  scientists, a couple incredible robots and a spaceship flying around,  Cooper’s team couldn’t tell anything about the planet’s inhospitable  conditions without trekking out to a glacier? And how would seeing that  one glacier really tell you anything about the rest of the planet? Like  with the videos-from-Earth device, the answer seems to be: Technology in  
Interstellar only works as much as the plot needs it to work.  Which is true in all movies, particularly sci-fi films, but it’s not  supposed to feel like it.
 9. Ultimately, if aliens/future humans wanted to save us, couldn’t  they have simply given the professor the secret equation? Especially if  the solution is apparently simple enough to be delivered by Morse Code?  Or perhaps give humanity way to grow some food? Rather than  orchestrating a spectacular protracted and complication mass starvation  family melodrama mind-f—k? Cooper was almost killed a dozen ways before  he gets into the tesseract; it just really seems like a lousy plan.
 10. We’re somewhat sure a planet, and very sure a ship, and absolutely sure a person, 
can’t get as close to a black hole as they do in this film. Unless we’re playing by the rules of Disney’s 
The Black Hole.  And if love is a powerful inter-dimensional force, do other emotions  power other dimensions? Like is there a sixth dimension fueled by shame?
 11. Where is the robot when Cooper is in the library den of the fifth dimension tesseract?  Because he’s talking to it but the robot doesn’t appear to be in the  same place. And what sort of radio works inside a black hole anyway? I  guess the answer is “because the fifth dimension makes everything  everything.” And do we buy that brilliant scientist like grown-up-Murph  decide that the answers for solving humanity’s crisis all reside in her  childhood’s poltergeist bookshelf?
 12. What’s on the bottom of the robot’s legs, exactly — are there  wheels? Wouldn’t it be scraping along crazily against everything with  those big square metal ends? At the very least making a lot more noise?  Still, I want one of those robots. The robots were rad.
 13. So at the end of the movie, Cooper is 124 years old in  Earth-time. Enough time has passed so that humans have created awesome  circle-vision space stations with softball fields and are growing fields  of crops that they apparently couldn’t grow on Earth. But are we to  understand they still haven’t gone to Planet Hathaway yet? And since  Brand didn’t do the time-slowing black hole plunge with Cooper, and  isn’t on a planet on the edge of that black hole, wouldn’t she have also  aged several decades too by the time Cooper reaches her? Did anybody  else want McConaughey to paraphrase 
Dazed and Confused: “That’s what I loves about space travel: The women get older, but I stay the same age”? (Perhaps Cooper, as one theory goes, 
actually died).
 14. Since it’s been established you cannot truly communicate from the  settlement planets back to our solar system beyond rudimentary pings,  how did Cooper know Brand wouldn’t be living happily on the planet with  the other guy — Edmunds. For all Cooper knew, he’s going to show up and  be like an awkward third wheel on her date for the rest of his life. Or  was he just banking on the other guy to have died by then, but Brand  still be alive? An even better question than how does Cooper know all  this about Brand: How does his 95-year-old bedridden daughter, who just  woke from two-year nap, know all this about Brand? And did anybody  expect Edumnds to be played by a surprise appearance by Joseph  Gordon-Levitt? Which leads us to….
 15. Cooper spends the entire movie trying to get back to his daughter  … and his daughter spends the entire movie yearning to be reunited with  him. He spends two minutes with her … and then then they both agree he  should split to go have presumed only-guy-on-the-planet sex with Brand?
