I guess I just don't get Adam Lambert. I seriously don't understand why he's such a favorite last year (I also didn't think Kris Allen is *that* special, but that besides the point). The screaming thing he got going when he doesn't know what else to do is simply far away from what I would call 'music', not to mention 'good music'. Sure, Lambert had his moments, but Andrew Garcia had his 'Straight Up' moment too, and in the end we found out that he's really just average.
Lee Dewyze, just for comparison, is like the new and super improved Kris Allen 2.0. More and more comfortable performance, creative arrangements, and he seems to know what he's doing (song choice, etc). He might actually win this thing.
I agree with the rest of your post though. Crystal is so much better than everyone else at this point.
