I've never been to a rave before, so I can't say anything about how realistic this film is.
I've also never used drugs before, but I really liked the way drug use was portrayed in the movie... One of the characters mentions that when it comes to drugs, it's best to be "baked not fried," which I interpreted as "using not abusing." The parallel threads we see evolve throughout the film observe people who don't use drugs at all, others who use them, and others who abuse them... All but the last case end up decidedly happy and content. But the film also remains very open minded and non-judgemental about the abusers; it refuses to condemn them, but rather it simply shows the results of what they do and allows the audience to form an opinion of these people on their own.
Another interesting theme I noticed was the fact that although raves are a great experience, there might be more to life than having a good time... One of the ravers explains how she has spent her entire life going to raves and has enjoyed herself, but somehow feels unsatisfied about what she's doing with her life. The idea that people must face fear in their lives in order to be content is presented, but a conclusion is never made, once again allowing the audience to use the film as "food for thought" and figure it out on their own terms.
The soundtrack to the film is great, as are the visuals... The movie has a very energetic feel to it that really made me want to be at a rave, even though I might not end up liking it.
If you want an interesting slice of American filmmaking and generational portraits from the 1950's, 70's, and 90's, I suggest consecutively viewing American Graffiti, Dazed and Confused, and this film. All of these films are done in a fairly similar style (following multiple story threads at the same time, being non-judgemental about the characters) and have a very feel-good atmosphere about them while still portraying the atmosphere, lifestyle, and challenges of a generation in a very interesting and entertaining way.
