Schoenberg was original, and was often mocked as a result. Even though he was easily one of the most gifted composers in his milieu, he watched as other, lesser men got all of the praise. Even today he is grossly misunderstood by the majority of people who know of him, which is a very small group to begin with.
Originality is generally a curse. Of course it can also be a pose. But to assume that all originality is a pose is to be a philistine.
@ Cordelia:
So, no you don't have to be a musician to be a critic, but why not do something positive instead?
