It was the 1st episode for Christ sakes, he had to address the NBC situation.
Did he shake things up insanely? No, the talk show format is still there, but titling the show and the opening segment was amazing along with the song at the end. Maybe a lot of people were hoping something along his lines of the tour.
He did seem a little more audience friendly, in terms of actually interacting with them. As long as he brings the edge of Late Night, with a little confidence, he'll do fine.

Picking between Conan and Comedy Central.
