I stopped even considering watching those movies after I spent 90 minutes with 'Not Enough Teen Movie' back in the early years of college. As we sat in my friend Kevin's dorm room inhaling pot flavored incense, I felt that it was the movie, not the smoke, that was making me stupider. In fact, to this day, if I ever have a lapse of judgment or say something inadvertently stupid (which happens more often than not), I blame that movie.
To cut a long story short, I'd eat my own ass than watch one of those things. Pay money? Pah!
