I enjoyed it. I thought it was worth my money. Co-writer Joss Whedon is, I believe, responsible for the movie being so awesome. It's like playing on that horror cliche of, ya know, the cabin in the woods, hence the title. Except it's clearly self aware. The characters are still making stupid decisions but they pretend as if there's reasons why those stupid decisions are happening. And the end is a clusterfuck of awesome. Most satisfying ending and definitely one of the more original movies I've seen in quite some time.
