He is just not funny.

I wasn't sure it was just me but yeah - he comes off as WAY too hyperpartisan for the mainstream. I mean, its fine for a medium like Comedy Central, where that type of zaniness is more or less expected, but even Letterman attempted to come across as toeing the line so as not to come off as alienating a significant chunk of the viewership (even if he started to jump the shark post-2008).
I maintain to this day that the more natural successor to the host position was Craig Ferguson, who from the looks of it is no more or less liberal than Letterman or Colbert, but who wouldn't have pulled obnoxious/polarizing stunts like drawing a Swastika to explain Trump's views on immigration post-Orlando shootings, let alone crashing the 2016 Republican Convention dressed like a Hunger Games emcee in a turban. As of now, I've never seen a mainstream host draw this type of negative attention to himself.

yeah I agree I hate when he does those high leg kicks and dances w/ the guy in the band. they should get younger and fire this old guy

This guy needs to retire the dancing

I don't think its left leaning indoctrination but I do agree it is not that funny

like Jimmy Fallon who is much more talented and funny
omg too funny.

Fallon is a talentless suck up. "Oh my God, I love you, you are the best, I love you, you are the best ever"

Haha I know!! I like Colbert he does a good job, I'm sure they'll give him time for ratings

Hahahahahahahahahahahahaha

I still don't understand why he was given a network night show. He is into satire, not stand-up comedy. He cannot compete with someone like Jimmy Fallon who is much more talented and funny

I have tried watching it when I was flipping channels and it is just unwatchable, it has very low ratings, is not funny, only reason he still has a job is because he tows the liberal line.
