Interstellar was incredible.
If i'm trying to be critical though, the ending felt a bit patched up in a way. It had it's merits there but the main strength was the way the film built tension and portrayed emotions. Pretty sure it had a bit of everything.
The plotline just kind of enabled them to do that I think, kind of a commentary on human nature.
Go watch it in the cinema, I guarantee you won't feel the same way about it at home. You need to feel it. As Corkin said, the sound is SERIOUSLY loud at some points. I'm not sure if that's to contrast the complete silence in some scenes though? Either way, they probably could've done it without blowing out eardrums.
