I have read the other reviews and think that most of the other reviewers are aging hippies that saw this movie in the '70s when it came out. The music was great and imaginative. The stake out scenes were too long.There was probably 30 minutes during stake outs that had maybe 4-5 pages of dialoge. Anyway the ending was typical of the time like "Billy Jack" or Easy Rider". Show the cops in a bad light and let the rotten drug dealer get away. I'm sure it appealed to teenagers back then, but not today where we have 30+ years of hindsight on the drug scene. The mark of a great film is how soon would like to see it again. The answer in this case is never. I would rather get a root canal!
