Saw Knowing the other day. I really liked it, and was shocked to find out how many people hated it. I hadn't read any reviews or heard from people who had seen it. It got 32% fresh on rottentomatoes.com WTF! Don't let your hatred of Nicholas Cage, and negative critic scores prevent you from enjoying one of the best recent sci-fi films, at least IMO. Worth it for 3 really amazing SFX scenes alone. I even liked the ending, which people seem to piss on the most when bashing the film.
Timecrimes was pretty good. A nice time-travel movie that is quite fun, and not insanely confusing. But its still kinda complicated.
