Gotta disagree with you there. From what I've observed, most people here (myself included) seem to think that the biggest problem with "the turn" is that it happened too suddenly, that there wasn't enough setup, incentive, etc. Whatever the case, it just happened too fast. So I have to give Lucas credit for not having Anakin follow Palpatine as soon as he revealed himself to be a Sith. At least there was some internal debate going on. Not nearly as much as most would like, but at least it was something.
