I agree with most of what you say.
I also see less then optimal choices, bad puns, tangents, pop culture references, and innuendo.
Soo if I say "Critical Role is just like my home game", those are the things I am speaking off.
I haven't watched a ton of CR, but it doesn't seem all that different from my games overall. My players include a professional voice actor who obviously does a lot of in-character acting, and a professional WoTC-published author who's big into characterisation; they're exceptional at what they do, but they're not a million miles from many of the other players. And as a University lecturer I can hold the room, prevent excessive digressions, keep things focused, etc. And I have an easy answer to any question.
I have had players tell me of other groups that aren't like that, but I've certainly played in groups like mine.
