So much is lost in the delivery, nuances in dialogue etc.
Plus, they ended baggage with some tacked-on to-be-continued storyline of their own, about the brother meeting some girl and her father in a bar or something.

You obviously don't know what you're talking about. Raymond is a very funny sitcom featuring actors who've been in the comedy game for decades, and successfully. So they must know what they're doing. And if you find the show so unfunny, why are you even interested in a documentary about the making of a Russian version of the show? I get the feeling you are of Russian descent and felt slighted.
