Just chiming in, because I went into Spelling Bee with a lot of trepidation since I didn't like A New Brain at all, and ended up really enjoying it. Though I would have to agree the score isn't it's strongest point; I think the book is, followed closely by the cast. I enjoyed it more than just about any of the other new musicals (ok, I haven't seen All Shook Up), though I realize that may have been in part due to my lower expectations for it. I'm not sure how it will fare as a Broadway show...though I think it works quite well in the Circle in the Square space, it really is a small, intimate show, and I can see where someone would have trouble justifying $70 for it, let alone $90, if they are expecting a lot of Broadway flash.
I think anyone who really thinks the creators believe being smart is something that should be ridiculed missed the boat. Is being smart something that is ridiculed? Yes, at least it was to an extent back in my school days, and I think that's what the writers are drawing on. (Although even I would have to agree that a couple of the characterizations are a little extreme!)
