It's very uncommon for me to see a Brazilian film, since they're always poorly executed, produced and acted-- and I'm Brazilian. "Paraísos Artificiais" is no exception; bad acting from most actors-- only a few did their job with quality. Directing is just poor and lifeless. Producing is lame, you can easily notice the parties aren't real since the ravers all do the same thing at the same time, which reminds us they rehearsed to do that. Story is vague and shallow. Rave is a good subject and with a professional production team it could have been a thousand times better! However, comparing "Paraísos Artificiais" to other Brazilian movies, it is not THAT bad. Just simply bad. Avoid it.
