I saw "Interstellar" this past weekend. Pretty good sci-fi movie, IMO. Very interesting on the science/physics side, and also very engaging on the personal and emotional side. And, at times, pretty exciting. Long as hell, though, but it passed well (unlike the last Transformers movie, where I was checking my watch every 5 minutes).
Lots of funny butthurt on the internet about the movie, too, from science writers and such. But don't read any of that until you have seen it, because the movie is extremely spoiler-vulnerable.
