This film is nearly indescribable. It ranges from interesting and funny (often hilarious) for the first part of the film, to a trip into the depths of hell. It has been said, in reviews on this website and elsewhere, that it is a movie for drug users, yet I beg to differ. If anything, this film, along with the great "Requiem for a Dream", is the greatest anti-drug statement ever put on film. It is not only an EXTREMELY accurate and fascinating depiction of drug use, but a disturbing depiction of the complete hell that drugs can put one in. See it once, and you will come out of it feeling as though you have a hangover. See it again, and again, and you cannot help but be entertained. The performances are awesome, and Johnny Depp manages to be riotous at times. The dialogue, particularly in the voice-overs, is biting, witty, and intelligently funny. Intelligence is not what you'd expect from your typical drug movie. It is beautifully photographed, and has a great soundtrack. Terry Gilliam, the brilliant director, has said of his film that you will not like it upon seeing it first, and that you may well have no idea what is going on. Repeated viewings will register the film as great. It will make you laugh, cry, and wail in misery, but the end product is, I'm convinced, one of the masterpieces of recent cinema.
People say Fear and Loathing in Las Vegas is "not for every taste", but really now, what person on earth could have this taste? It is not a matter of taste, for this film defies taste, it has no taste. Anyone is capable of seeing it and enjoying it. Just give it a chance, it's such a monumental effort.
The entire film Fear and Loathing in Las Vegas I think can be described as the character Dr. Gonzo (played by Benicio Del Toro) is in the very end of the film:
"Too weird to live, too rare to die"
