Not a "great" movie... but pleasantly original, humorous and entertaining.
This is a horror movie that really isn't all that scary... nor does it particularly try to be. Rather, this movie uses a typical "horror" scenario and cast of characters as a loose foundation... and the writers riff like jazz musicians from there.
Without giving anything away: there is a nifty infusion of philosophical ideas into the plot. Ultimately however, this infusion is superficial and not seriously delved into. I left the theater thinking that if the writers went in a slightly different direction and put more "uumph" into the intellectual side of the movie... The Cabin in the Woods could have been a revelation.
As it stands, though: Cabin is a fun ride that ventures into unexpected/unexplored territory. Take it for what it is... and that's not too shabby.
Brought to you by Joss Weedon and Drew Goddard of Buffy the Vampire Slayer fame. If you are at all familiar with this TV show... you will recognize some similarities in style between it and Cabin (both are a little campy and off-beat). That being said: I was never a big fan of Buffy... yet I enjoyed this flick.
I recommend for a good (not great) night at the movies. Here's the trailer:
