Although Neil Degrasse Tyson spoke highly of the science, and Adam Savage thought the robots were really cool, Interstellar is a less than stellar movie.

It was largely predictable, and I never really worried about the characters.  The ending (once you watch it) seems convenient and kind of flat.  Apparently the original ending made more sense: http://io9.com/interstellars-original-ending-actually-made-sense-and-i-1692640631

The Good: Spaceships and satellites seemed as fragile as I imagine they truly are.  Robot AI was cool.  Matt Damon!
The Bad: Matthew McConaughey seemed more mumbly than usual.
The Ugly: I cared more about TARS (the robot) than the characters
