I wouldn't ask Colbert to go back to the CR exactly as is, but I would appreciate more of the creative energy and ingenuity from that period. Outside of his monologue, my wife and I find that a lot of his non-interview segments fall flat on The Late Show. The only segments I tend to like are the ones cribbed from CR anyway. His interviews are generally always solid, so no complaints there. But when I think back to CR and all his epic-tier skits/segments: The Word, his parody video for 'Get Lucky', Better Know a District, his segments he did with his BIL lawyer exposing how super PACs work, his coverage of migrant workers and the hearings he attended in Washington. Etcetera. So much of that could be adapted without the need to pose as a fictional character to do it. But I guess the audience isn't ready for it? IDK.
