[Q]: 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.
[A]: Positive


[Q]: I haven't been able to watch this much because the DVD won't play in my normal (otherwise functioning) DVD player. It will play on my computer's DVD player, but without sound. The DVD will play fine on my laptop, but that's not a screen that's very conducive to practicing in front of. The DVD does play on my friend's DVD player for some reason. Also, I bought volumes 1 and 2 and both are so short, it seems obvious that they could have put all of the lessons on one DVD. I guess they knew they could make more money by making us buy both.
[A]: Negative


[Q]: I'm very pleased with this product because it has a natural feeling head and makes climaxing easyand can be used in the bathtub,shower or where ever.
