Query: Tragic, intense, and frightfully scary..

This movie was gripping from the start to finish. I loved how it opened- a bunch of kids who obviously have minds of their own- getting high off of some household cleaner or something, skipping school, ripping off hot dog carts.. and you think this all seems crazy but then ultimately all the hard core drug usage starts and while at first it may seem like nothing but a small enjoyable thing to do- it soon is a huge habit for Jim.Watching all the struggles Jim has to go through- loosing friends, trying to be clean & then failing, prostitution, begging for money, getting into physical fights.. - it is hard to watch and you physically can't believe that someone can go through so much and come out victorious in the end.Leonardo plays this role FANTASTICALLY. Especially the part when he is crying at the door begging for some money from his mother. The amount of passion he pours into this character is huge... for that reason alone- go see this movie.
