I saw Timecrimes, which was pretty good. It's a kind of dumbed down version of Primer, which is the only movie I've seen that I thought desperately needed dumbing down.
Before Timecrimes, the Alamo showed other movies by Nacho Vigalondo, including
7:35 de la Mañana. I saw it once before in a set of Academy Award Nominated short films. I can't believe I'd forgotten about it because it's really incredible.
