I never posted my thoughts on Interstellar. Here's the short version.
This is an admirable, but flawed film.
First of all, it's great to see a mainstream science fiction film about space exploration. The overall premise and general progression of the story is intriguing. The twist involving Matt Damon's character was definitely one of the high points of the film. The robots were magnificent. The segment of trying to dock over Matt Damon's planet while nearly spinning out of control was very exciting. In principle, I don't mind the pastiche of a main course of hard science fiction with a few helpings of the paranormal. In terms of tone, there was a nice blend of Close Encounters, Contact, Gravity, and 2001.
Where the film failed with me was in the execution of certain important segments. For example, consider the time dilated planet with the giant tidal waves. It was completely unbelievable that conditions on that planet could not be precisely anticipated. The hydrodynamics determining the tidal waves should have been just as predictable as the time dilation effects, given the arrangement of masses in orbit and given observations of the planet to determine surface composition. Now, the original astronaut they were going down to try to rescue may not have had any choice but to land there, but the follow-up party really should have known exactly what to expect. Yet they were surprised and caught flat-footed on the surface. Very bad writing there because it was completely implausible, despite being dramatic and suitably frightening.
The idea that the whole space program depended on solving equations that no one knew how to solve was also very hard to take seriously as something from the hard science fiction genre. No, that skews the film's genre towards fantasy, but for additional reasons beyond the solution of the equations being by fantastic means. The space program struck me as kind of like a cult.
I thought that the ending was awful. Catwoman going to sleep, fine. But lover-boy going out alone to wake her up with a kiss, uh-uh.
The central heart of the movie, that humanity will survive extinction because of our inherent godhood is, well, of the fantasy genre. But that's what unrestricted time travel is, as demonstrated by Bill and Ted, the ability to summon garbage cans out of thin air on the promise that you will throw them down later, or in other words, the ability to wield godlike powers.
Again, I said short version, so, moving on....
So, the other reason I haven't chimed in until now is that I really don't know how to grade it. Part of me wants to give it an A for effort, but the demerits nearly knock it down into the B range. There are so many science fiction films that are better, but none of them are contemporary, except Gravity. On the other hand, there's a lot to chew on, so the film earns back something just for that. It's certainly worth seeing.
