I thought the episode with James Damore was a good example of Joe ruining what could have become an interesting interview: lack of direction, ranting, pushing James towards particular statements. But I don't mind his show being hit or miss, given the sheer number of episodes.
It didn't help that Damore was a terrible interviewee. He was clearly nervous and awkward and not particularly good at arguing his viewpoints. I put more blame on Damore sucking for that one than Joe.
Exactly, he generally seems to get dragged on by the guest, especially if they have a strong personality. Someone like Neil DeGrasse Tyson will call out Joe on make he starts saying bollox like the moon landing conspiracies. But then other people will go on the conspiracy path with him and let him spew shit neither of them understand.
