I don't know about that. There is nothing logical about immediately jumping to, "Hey, we just signed one of the biggest stars in the history of wrestling, so let's risk making him extremely unhappy right off the bat by bringing in his ex-wife before even talking to him about it or seeing how he feels." There's no way Randy wasn't involved in those discussions, so I don't think it's a stretch that he's the one who lobbied to bring her in.
I have no idea why Meltzer is being bitchy - I haven't read his tweets and avoid most of them - but the first episode was pretty decent. Maybe subsequent episodes go off the rails? I don't know. The Brody one seems highly talked about, both here and elsewhere, but I haven't seen it yet and won't until Amazon adds it.
