No problem, I'm glad you enjoyed it. I love the first movie too, it was wonderful and like you said did a lot to turn people on to the scene...this one not so much...the words train wreck and embarrassing come to mind. Try to track down the third if you can, I haven't seen it in years but it revolves around homeless punk rock in the late 90's around LA. If I remember right it was pretty fascinating.
I don't know if you've gotten to it yet but if you think the Simmons/Stanley shit was corny wait until the get to the part with Chris Holmes of wasp, its almost horrifying in a way. OH and my god, the stick up her ass women with her "heavy metal deprogramming" program, seriously how much more 80's rock could you get with out a puritanical battle axe going on about satan and heavy metal.
But yeah that whole scene was just a giant microcosm of what the 80's were all about excess, fame, money, designer drugs, irresponsible sex (at the height of aids hysteria none the less) and this film really did a good job turning the glamor that stations like MTV worked so hard to associate with it into something that just looked kind of sad and ridiculous. Average Joe music fan just couldn't relate to the bands in this film in the way they could in the first one and it probably did more to turn people on to the burgeoning college/alt scene, early grunge bands (a lot of those bands were getting signed around the time this came out) and thrash metal then anything else.
Hope you enjoy the rest and look forward to hearing what you think, I always love a good discussion about music.
