overall, the documentary was pretty cool. however, about 99% of the beach boys clips were from a prior documentary, an american family from '85. they should have included the clip of dennis singing manson's song never learnt not to love (aka cease to exist). especially since the title of the movie is the beach boys & the satan. but did have cool footage of interviews with dick dale and dean torrence and the chantays. also kim fowley was cool too.
Positive

I was extremely disappointed with this movie. The story had no sense of direction. It seemed too badly glued together, as if the scriptwriters were just adding more things as they went along, saying, "we'll make her a divorced woman...and then we'll make her go on a gay tour...and oh wait, let's make her have no morals and have sex with a man she hasn't known for even one day...and lets make her flirt with the married real estate man." All in all, the story turned out to be pretty stupid with nothing to admire in the main character.
Negative

the special effects sucked and we've seen good special effects and the special effects in the odessy were crap and in comparison to a lot of movies we've seen it was pretty crap. it was realy BORING! (...) we've seen and weve seen heaps of them and some of them were realy gory over all COULDA BEEN BETTA!!!!!
