Se7en is a movie that came out back in 1995. It's about a serial killer who chooses his victims (and the nature of their demise) according to the seven deadly sins. Brad Pitt and Morgan Freeman are detectives trying to catch him, tracking his clues but always one step behind. It's one of the best-made, most engaging crime films ever created, and builds to a shocking final scene. It's top 10 material, and it's a lot to live up to if it lingers in anyone's mind. Of course I also noticed some aspects in the thr3e trailer that remind me of Saw, and so people will no doubt compare it to that as well. People already compare Saw to Se7en (also spelled simply "Seven"), which is unfortunate for the former because Saw is not nearly the movie that Seven is. That said, if the movie stands well enough on its own, the inevitable comparisons won't matter as much. Everyone seems to like the book, so I hope the movie will be good too. I'll refrain from prejudging it and try to see it soon.
