Seriously...?
What annoyed me the most, was, that early in the film, the college kids are seen smoking a joint and later the black guy is pointing out to one of the girls, that smoking is bad.
So, joints = good, cigarettes = bad.
Now, I'm a smoker myself, and do enjoy the occasional joint, so I obviously have no problems with movies depicting either - or movies depicting neither, for that matter.
But it annoys me, that for a movie that wants to push boundaries and be over the edge, they HAVE to push the anti-smoking agenda - in an R-rated movie, no less. If you're gonna show it just to throw in some anti-smoking crap, then leave it out entirely.
...just sayin'...
