I don't understand people who go out of their way to try to poke holes in the scienctific accuracy of movies like this and Gravity. It's a fukking movie, not a documentary. Just enjoy it.
Anyway, I loved Interstellar. Will definitely be seeing it again.
To be fair, this movie brings that on itself. The astronauts spend a good deal of time taking directly about the science of the mission. It was a major factor in the plot. Hell, it's basically the crux of the film's final act.
Very different than Gravity in that aspect.
