I agree, I really didn't get drawn in by Interstellar much at all. Although I only watched it on a home "theatre" and not an imax blow-your-mind "experience", so maybe I missed out on something that the bigger screen would have given me?

It's just weird that a rapidly-falling-back-to-agrarian society scrabbling for resources would also be able to secretly maintain such a high-technology base. I was waiting for a 1%-esque hidden society to be revealed leeching off the masses or something.

I'm not sure what the agrarian bit meant, I felt like it could be dropped without losing much of the film. I would have believed a dying Earth with every effort thrown into trying to colonize Mars, but Martians get cancer and the colony keeps failing or something. Then we discover this wormhole with what looks like Earth-like planets right on the other end! I could believe we'd throw a lot into a last ditch effort to find a planet we could live more easily on.

I probably over-thought it :)
