When I started to watch this movie I wasn't at all aware what it was about. I just saw that MaCaulay Culkin and Seth Green were in it and thought, "Cool! Maybe this'll be good." A lot of people say this movie was bad, that it was horribly acted, but I think they just couldn't get past Culkin's shortcomings. I don't believe he was a bad actor, I simply believe he got stuck on the idea of how he had to humanize his character, and that was his ultimate downfall (in the special features he explained this was something he wanted to bring to the character).
Seth Green, as always, is adorable and can completely immerse himself into a character and really bring him to light. Marilyn Manson played Christina wonderfully, if only for a short time. Wilmer Valderrama was terrific as Keoki and it was a disappointment to see he was only in such a little portion of the film.
All in all, this movie was great. It had a great cast and a great script. The movie was meant to poke fun, not to make you think about any hidden meanings or to wonder why they were acting so strange. Club Kids were all about glamour, mocking celebrities, and, in the end, drugs. They didn't want to grow up, and they certainly didn't want to live a normal life.
Culkin had his moments where he pulled Alig off well, and in others, you could tell he was trying to stretch the character into places he wasn't meant to go. And if he was, Culkin certainly wasn't the actor to do it.
All in all, a "fabulous" film. Highly recommended if you're interested in how some of the 80's really played out.
