People not getting it
I think most people are missing the point of this. It's an homage/parody of celebrity Christmas specials done in decades past (the Bill Murray/Chris Rock skit is an obvious take on the Bing Crosby/David Bowie special). It's not supposed to be classic, silly Bill Murray stuff... which is actually what I was expecting when I started watching this. But I quickly realized that it was something else and enjoyed it for what it is. Please tell me I'm not alone in that.
The only criticism I have is what others have mentioned; why are some portrayed as themselves while others are acting as fictional characters?
