What the F*ck. 

It started out pretty slow, let us get to know that all the characters are pretty horrible (even when they try not to be). The surf trip was wild, I was shocked that none of it was made up by Remy. I thought for sure he was hallucinating. 
I didn't see any of the twists coming, but I found alot of them hard to believe, the horror twist fell flat for me.
