I'll take a step back from the "show is lame" stance I took. I've tried to watch episodes, and I've wanted to like it, seeing that Carson seems like a cool person off the show (gathering this after listening to "Loveline"). My biggest beef is that Carson doesn't seem to know which direction he wants to take with the show. When it first started, it was a laidback, informal show. I don't think there was even a monologue, you had the intro, then dissolve to Carson already seated. The show then switched up to a Leno look-a-like, all the way down to the set and skits recycled from every other late night show. It's almost like he doesn't know what kind of audience he wants, although I guess you could say he just wants to appeal to the masses.
/Must give him credit for that Coin Toss game show idea, tho.
