I'm Mr. Science Skeptic and sometimes this spoils SF movies, but in fact, it's really the humanity of the characters that I care about.

Point in fact - Gravity. Yes, a couple of scenes in the movie didn't do Newtonian mechanics right, but no scientist emitted any science howlers that made me cringe, and more, the characters and their motivations rang true. In particular, there was none of the abject, wilful stupidity that seems to drive the plots of other films. People made mistakes, but generally tried very hard to do their best.

I thoroughly enjoyed the film and would recommend it to everyone.

Interstellar, on the other hand, was one of the worst movies I have ever seen, and the bad science and economics were the least of it.

It was the poor choices of characterization which made the characters into inconsistent robots doing stupid things in order push the plot forward, not because real people in that situation would act that way.

I'd add that I loved the Martian for much the same reasoning. When Damon's character, abandoned on Mars, announces that he is going to "science the fuck" out of the situation to survive, I misted up.

As you pointed out, the mechanics of the last scene are just wrong, and it didn't bother me. Well, not very much.

Thanks for yet another fine article!
