talking jive, you will LOVE San Andreas. I get that current scientific knowledge sometimes has to take a backseat in these disaster movies, but San Andreas doesn't even try. 2012-level bad science. On the flip side, the movie has no qualms about objectifying its female objects, some of whom are aesthetically pleasing, so if you are into that, you will love the movie!
Interstellar, on the other hand, is great. Very thought provoking movie. If you don't mind long sequences where it sounds like Hans Zimmer fell asleep at his organ (thanks Honest Trailers), it is engaging the entire film. I didn't mind the ending, though it wasn't perfect (I don't want to spoil). One of my favorite films from the last few years.
