i decide to watch this film recently after see south park make fun of heavy metal in the so called cheesing episode . kenny and stan dad get high and enter the very sexually charge world of heavy metal . i give this movie 3 star for one reason alone the music be exceptional and though why they include journey open arm along with all the harder rock and i will never know . the tune and if you love late 70 early 80 hard rock and be really good . a for the rest of this film and it play like a teenager wet dream a animated and direct by a group of not particularly talented teen . the first thing that many viewer will notice will be that the animation make the bad hanna barbera cartoon of the 1970s look pretty good in some way . that because the frame rate of heavy metal be very and very low result in an even jerky and less animated style of animation . people who have give the film score of 10 must either be blind or just could care less about super cheap animation . now that doesn not mean the animation be all bad some of the background and a few of the scene be definitely well than hanna barbera but even the best this film have to offer be light year bad than anime and such a akira . although i saw review that compare the two and akira be simply a much good product animation wise or traditional full length cartoon . apparently the different segment be the work of different animation team and though none be particularly good . another thing you may soon notice be that although this film manage to get an r rating and it be incredibly explicit yet somehow this get the r and fritz the cat get an x. while the language wasn not that of fritz and there be ton of naked people feature not just breast but crotch shot and sex lot of sex . now i could see how a teen might like this and but for anyone want porn and they could also do a lot well . see exceptionally explicit cartoon just seem sleazy and kinda gross . so what you have be a long series of short smutty story that be horribly animate that be set to great tune . my suggestion be that you watch the cheese episode of south park and see their dead on parody of heavy metal instead it actually funny and worth see unlike this rather stupid film . i can not believe i actually watch this dumb movie .
