Cabin in the Woods (2011)

Love love love this movie!  I watched it twice already and will watch it again.  I am not buying it because I really don't want to buy movies any more - too much plastic.  Maybe I can get it used down the road.

Five friends (important number) go to a cabin in the woods for a weekend of debauchery.  Instead they get Evil. 

This film was written by Joss Whedon.  If you watched Buffy, and you liked Buffy, you will like this.  It's about as scary as Buffy (so not scary), and even more clever and witty and outrageous. There is some gore, but it is ridiculous.  The gore and the effects are not the point here. The dialog and the wonderful premise are the point.  The ending is fantastic.  The send-up of traditional horror is lovely.

Here's an indication of cool level.  Fred and Andrew from Buffy / Angel fame are in the movie, as are Richard Jenkins (Oscar nominee), Bradley Whitford and Sigourney Weaver.  No. Shit.  Pick this one up.
