This review may contain spoilers. I can handle the truth.
My brain melted. But first it was cut into little pieces and then grounded. The dust was mixed with water and stirred until it's texture was that of a chocolate milkshake. Then, it was left outside in the sun for almost two hours, in which time it melted.
I dislike the horror genre. I really do. I've tried with old monsters, demons, ghost stories, and with the modern "jump scares" movies. I can't stand them.
The Cabin in the Woods for me is one of the best movies released this year. It may not change the genre, but it gives it something fresh. I would watch more horror movies like this. Movies with an actual script.
Now gimme a spin-off with the control room guys, Whedon.
