Worringly bad. Re-used jokes. Basic humour. Too much prompting the audience to laugh. Re-cycled jokes from other comedians (including, ironically, Brendan Schaub). This is borderline offensive to the many innovative and creative comedians in the world today.
The most annoying part is that Rogan openly says he ignores all criticism online because we are just plebians with no worthy opinion. Instead of taking feedback on this, he will see it as a success.
