I got to see The Cabin in the Woods on Monday night courtesy of my friends at Ain't It Cool News. Because I'm cool like that.
This movie is impossible to review because I don't want to spoil anything. Let's see -- it's a horror movie, but not quite, mixed with awesome, clever, comedic Joss Whedon dialogue. It's a fun ride. It's original and scary and funny and unlike anything you've ever seen. And it makes you giddy after watching because it was so cool.
That's the best I can do. As long as you're cool with horror and gore - done smartly - check it out. It's just fun and generally awesome.
