I'm not going to review the first night because...it was the first night. Shows need time to develop. I'll just say that I think Colbert is a really smart guy, very talented and highly likable, and the first show was fine -- some things worked wonderfully, some just fair.

And if this is how he reacts to talking with a comic actor, it doesn't bode well for being president. Point of reference: Colbert did not ridicule him, and was quite polite, with only a couple of very mild, pointed questions, all of which Mr. Bush should be well-preferred for by now, but still doesn't appear to be. Seriously, how can he not be spot-on impeccably prepared for -- I'm sure you love your brother, but how do you differ from him on politics?
