I wanted to add if you're going to this movie for game movie action like Star Wars, it's not your movie, but still worth your while. It's got great action but the action is important to the story and not just flash and flame like a lot of the bigger movies, such as Transformers and Star Wars.
I don't know if the new Star Wars coming out will get back to a more human level, but the last three were very disappointing on the level of heart.
Interstellar is driven by heart, not by lots of special effects, of which there are enough, but not so much that they bury the true purpose of the movie which is to show what makes humanity special...our hearts! Not our guns, our power, our fame, our fortune, our politics, our wars...our heart!
