Cabin In The Woods

So this is what happens when you take a sturdy base of Evil Dead, throw in a pinch of Cube, a dash of 13 Ghosts, a dollop of Truman Show and stir.

5 lucky "college kids" (they all look to be about 30) go to a cabin in the woods for a weekend retreat.
Once they get there, they're locked into a fucked up sort of reality show.
Behind the scenes, the 'producers' take bets on their fate as the kids explore the cabin and die one by one.
There's a bunch more meat to this story and of course it was done really well.
This is Joss Whedon we're talking about.
I will say, the monster release party is an awesome one.

So fun, I'll give it 4 out of 5 Ancient Ones.
