For our viewing pleasure during dinner and after, we chose "Saw IV." Perhaps an odd choice while eating, but we loves us our scary movies.
Apparently this one went straight to video, so we weren't quite sure what to expect. We loved the previous "Saw" movies, because the stories were so unexpected (especially the first one) and suspenseful. They focused a little too much on the gore in this one, but the suspense was still there, and it actually turned out to be pretty good. It explained a lot about how and why Jigsaw turned into a serial killer...it was almost sympathetic in the telling of the tale, but at the end of the day, he's still a serial killer. Along the way, there were plenty of inventive and twisted ways to meet your maker. (Two words: ice blocks.)
I can't recommend it to everyone, unless you love horror movies. If you do, it's worth watching.
