Question: 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.

Answer: Positive

Question: I've noticed very little degrading of the sound, if at all, and this is rare in most extensions. The cord is thicker than usual for both the positive and negative polarities - a separate wire for each - and I'm quite pleased with this, will perhaps get another because of its thickness. I now have great headphone sound within a twenty-foot range - just what I was looking for. Even if you don't need 15-feet of cord, I would recommend this over the shorter 10 foot cords where the wiring is about half as thick and not likely to hold up over time...I subject all my electronics to heavy use. Plus, the best extensions for Grado headphones go for $40, and I'm quite satisfied saving over $30 by having this one.

Answer: Positive

Question: This DVD Trilogy box contains the two-disc editions of SM 1&2 and the single-disc edition of Spidey 3. However, 1 and 3 are available separately in 3-disc sets, and I'd be surprised if 2 wasn't given the 3-disc treatment right before Christmas. So, when the 3-disc editions of all 3 movies are available in one box (think Ultimate Matrix Collection), then that will be the one to buy. This box can be skipped.

Answer:
Negative
