I'm well aware of it's status and cultural impact. The only reason I've given it 4-ish tries is because of its clout.

Kind of has the same problem that Sons of Anarchy gives me. None of the characters, despite how well written they may be, are likable. If I can't find at least 1 character to identify or even sympathize with it's hard for me to keep interest. If the entire pool of characters ranges from "rat-bastard" to "evil genius" then I'm not gonna find it so great. I hate seeing bad people succeed, enough of that in real life for me to enjoy it as an unchallenged plot point in a movie/show/book.

With the Godfather trilogy I get that it's super highly regarded. And while I personally have no clue why after several attempts to watch and a lifetime of hearing references, I respect its impact on the entire film industry. Just not my cup of tea.
