You're kidding right? A lot of bands that played there/came out of there shaped the the last 30+ years of music.
I'd be ok with the movie if they based it from 'Please Kill Me', but I doubt that's what they're going by
Definitely agree with your point of bands not ponying up money to help the venue out. I was pissed off about that back when Korn was playing a show there to "help them out" and was saying 'how about you just give them 80k if you care that much?'
