Call me a Joss Whedon fanboy, but I simply loved Cabin in the Woods. Written by Whedon (Buffy, Firefly) and directed by Drew Goddard, this film is quite smart, parodying the horror genre frequently and becoming rather meta in places.
And it is for this reason, Cabin in the Woods might have not appealed to everyone, who might have expected a straight out horror film. It takes a group of young people, like almost every horror film, and sends them to a cabin in the woods. The setup is simple. What happens later isn't.
Is Cabin in the Woods too smart for its own good? Possibly. The film is low on the scare factor. But we're tired of simple scares. It's good to see a film that intrigues us with a plot that takes unpredictable turns. This is a worthy addition to the horror genre.
