Cabin in the Woods
Tucker & Dale Vs Evil
Stir of Echoes
Edge Of Darkness

All just looked like run of the mill movies, offering nothing new, but I found each of them very entertaining, far better than trailers or reviews may have suggested.

By far the biggest surprise for me though was the movie Goon. That looked like an awful, awful comedy with Seann William Scot, but turned out to be quite funny.

At first  before watching i thought cabin in the woods was just another horror alike thousend other movies in that genre but i really was amazed by how the plot evolves in something very unique and i was wowed by it.
