Warbreaker was about the same-- it had a lot of actual conceptual coolness which kept me reading it. The magic system, which was based on color, was original and nifty and I was interested in the larger metaphysical implications, some of which he even went into. On a character level, there were some thing that weren't stupid, and then there was the rest of it. I can't say it was a bad book, because I think it did exactly what it was trying to do, but I think that his goals as a writer do not match what I think of as what that sort of book ought to be trying to do. I have mentally filed him under 'pleasant beach reading, lots of cool shit, do not expect much, worth time if tired'.
