It's the Amazon Kne-Jerk Contrarian Game. Waxy has the right idea, the bad reviews are the most interesting, being written either out of sheer malice or by people who just don't get it. Here's a good batch on John Coltrane's "A Love Supreme"

* "Coltrane's A Love Supreme is the most overhyped jazz album in history. It is music? Maybe. But I find it to be unlistenable, despite several efforts to find something good in it."
* "The first number is torture if you like melodic music. There's no connection between the phasing and the rhythm. Again, is this supposed to be clever?"
* "Nobody will care about the technical achievements of these guys in 100 years."
* "I think about Kenny G., for instance. His rythmic session is much more regular, whereas Coltrane's session seems sometimes to loose the beat."
