I didn't realize a man with a robot sidekick who dances around with a sixth-grade play level two-man horse on a regular basis wasn't wacky enough for you.
Well Triangle Man, this is the difference between Carson, Letterman and everybody else as far as these late night shows have gone. If you want to watch celebrities play Pictionary and Name that Tune, then Fallon will be your guy. In fairness, I like watching those things sometimes too.
I barely remember Carson but the big change between Carson and Leno (and I'm saying this looking back on a change that happened a long time ago when I was very young and from an impression I've pieced together in reading books and watching old clips) is that guests came on the show with the express goal of impressing Carson. When you hear those in the comedy industry lionize the guy, I think in some sense this is the achievement they're all dancing around. Carson did a comedy show in which he was entirely non-reliant on the booked talent to bring viewers in. Carson was actually the show and guests came on because they respected him and wanted his approval.
Letterman is the closest we've had to that kind of figure in the last 20 years. Obama going on Letterman was an event. Obama taping a bit for Leno's final show barely registered. That's not about Obama, that's about how we perceive Letterman and what kind of interview you'll get with him vs. what you would get with Jay.
Obama has also been on Fallon, in a famous "Slow Jam the News" bit. That's Fallon distilled to his essence. The guest gets to feature in a bit that plays to their strengths and Fallon and the Roots will make them look good. Fallon will never have a moment like Letterman's interview with Crispin Glover, or Letterman with Joaquin Phoenix, or Letterman with Madonna. It's just not in his DNA.
In that sense, Colbert is a fitting choice.The man has always asked penetrating interview questions and, more importantly, seems completely unafraid to mock his own guests.
I don't remember Carson really, and Leno was fine at first but got tired for me after a while. Letterman was fine sometimes but for every one of those few interviews you talked about there were 100 that were dull and often awkward. Most of the top 10's had one or two funny lines, but the rest were lame. I think the Letterman band sidekick was too lame or cheesy, even more so than the rest.
I think Fallon while safe with the guests at least tries to do something fresh so it doesn't seem like it's the same night over and over and over just with a different guest.
I guess I'm the other way around. That late at night I just want to be entertained, and sometimes I don't mind seeing something awkward and strange but I'm not going to look for it every night.
Could be why they have different shows on, people want different things.
