The Girlfriend Experience - I watched this one because Steven Soderbergh directed it and it was described as "experimental". It stars Sasha Grey in (I believe) her first non-porn role as a top-tier call girl. It was not a good movie. At all. Sasha's acting was mediocre at best and the plot was sort of all over the place at times. Thankfully it was only about 70 minutes.
Deep Blue Sea - Better than The Girlfriend Experience but still not that great. One of those "Aaahh! Sharks are scary!" movies. But it did have some fun moments. I actually laughed quite a bit during the movie.
Trick 'r Treat - I loved this one. Four short stories are seamlessly blended together over the course of Halloween night as things inevitably go wrong. It's got a bit of camp to it but that definitely adds to the appeal. I can't believe it took me so long to get around to seeing this.
