Having nothing to do with anyone who fits that junkie sort of persona depicted in the movie (that's what its about by the way), I actually found this really interesting. My understanding of the movie was just a well enough produced tale of 4 addicts with their own problems, and how their dreams were shattered. I see how the title more or less fits, but it seems a little ominous (good thing).
Knowing very little of this lifestyle as I said before, I can't say anything about the accuracy or style of the story. I just found it not quite fun, but intriguing to watch. It seemed like a documentary almost, but without a voiceover by a famous voice actor. More controlled by the characters. So it's a movie that had that feel to it.
If any of that made any sense to you, congratulations, you now have an insight on how I think. In a way that makes no sense. Though I will say you should probably watch this if you live that lifestyle or not. It was eye opening in a sense that most other movies have not had for me.
