I still can't explain why I dislike Jimmy Fallon, JImmy Kimmel and Conan O' Brien so much

Cause they’re not funny but host comic shows?

Because all the late-night talk show hosts are formulaic, and they all have pretty much the same exact talking points between them. The only late-night host that I quite enjoyed was Craig Ferguson.

Sounds like you just don't like people who talk with you or at you but not to you.

What about Johnny Carson The OG Latenight Talkshow,Host

Craig Ferguson was the only late night host I ever cared about. XD

I like Leno. Not a fan of the rest of them.

what about Corden 👀

Is it the floppy hair?

Johnny Carson, once you looked and enjoyed his style, the others were/are generally imitation and crap 💩!

I'm guessing because none of those shows are entertaining.
