A screenwriter got really high, stared at this ...
... for thirty minutes, and began to write.
Review:
A group of recent college grads head on up to a cabin. They notice it's empty where they were expecting some of their friends to be there already. They further start to piece together some fucked up things that must have happened before they arrived and relate it to how screwed they are in the present. That's a horribly generic description but it's difficult to elaborate without spoiling the major twist.
The main hindrance to overcome is that half the characters are dumber than shit while the other half seem semi-coherent, but act like cowards or assholes when it matters. They appear to act on rational logic when the irrational presents itself very early on in the plainest and most permanent manner possible.
Verdict:
Has potential but the plot requirements get more and more off the rails as the flick goes on.
