Well, I guess I'm the third kind. I find the movie to be powerful in the depiction of the devastation caused by addiction. It does it's job excellently,it's also very gripping, but it's definitely not a joy to watch. I mostly become depressed after watching it. But I do watch it every 3 years or so :-)

Incidentally, I first heard the music when I watched the movie. The whole casting and TV selling and drug buying scene was framed by this music, and it felt very dirge-like. A foreshadowing of what was to come. And my mind associated it very strongly with those kind of tragic scenarios. But later I started seeing videos on Youtube about football or dogs with the same music.
