One thing, imho, that's problematic about free jazz is that there's no notion of "better" and "worse." It seems that everyone who plays free jazz is a "genius," which of course means that no one is. I haven't seen critiques that say this piece of free jazz is better than that one, and why, or that this solo is better than that solo and why, or that this musician seems more inspired on this session than at that one and why. There is no real analysis applied; implied is that any stretch of noisy music must be respected. There is no hierarchy. I can easily say that Ben Webster was better than, say, Stanley Turrentine, but that Turrentine was nonetheless very enjoyable to listen to.
