Honestly, I find the "they're not relatable" argument a weird one. These are wealthy celebrities, they're never going to be relatable to most of us. It's a completely different lifestyle.
People expect them to share certain things about their lives, such as holidays. They're not going to say "let's just go to Skeggy this year love, we want to seem relatable."
The complaining about working until the 20th is no different to what I'm hearing from the parents at school who have the officey type jobs and are moaning they don't finish until Monday, or moaning they "only" get a week off this year. And Rob's big rant about there being a lot going off and a lot of pressure in December was right. I've had similar conversations with other parents at school.
I do think Rob needs to rein in the interrupting and talking over people. I also think that the pair of them play up to their stiff neck/loose neck personas. I'd bet that neither of them are as extreme in real life as they appear to be on the podcast or on TV.
