While the acting was relatively good, this movie suffers from a poor plot and characters who aren't even close to being likeable. The main character has no charisma, what the drug does to him is hardly enjoyable to watch, and he comes across in the end as uncontrolable and unsettling. Ironically, he learns nothing in the course of the story. And somehow, the movie tries to paint him as a sort of hero. Thrown in with that are numerous stylized 'trip' scenes that add nothing to the plot. The movie left me thinking 'what the heck was that all about?' It was a really dumb movie. The only reason I gave it a 2 is Brad Cooper dragged it up out of the abyss with some ok acting.
