A place to talk about movies--old and new, good and bad, high art and high cheese. It's the place to place your kittens on the award winners, gossip about upcoming fims and discuss DVD releases and extras. Spoiler policy: White font all plot-related discussion until a movie's been in wide release two weeks, and keep the major HSQ in white font until two weeks after the video/DVD release.
