The Cabin in the Woods
It is good, but very strange. If you are hoping for answers at the end you will be disappointed. Clever movie, but I can't go into even semi detail about the plot without ruining it.
It's definitely worth watching.
No answers apart from everything laid out on a plate and explained in fine detail. What the Architect did for The Matrix Sigourney Weaver basically did for this film
Anyways, this movie throws quite a few genres together and ends up with a cross between The Evil Dead and Lost. It's got a fun mix of serious horror and tongue in cheek, I don't know how much of it Whedon was involved in but it seemed to have his staple humour in it. Really enjoyed this one so 8.5/10
