Did you watch it? I read the books and I'm really liking it. It very obviously diverges from the books early on, but I like to think of it as a different timeline, where things happened slightly differently. That's what it feels like, anyway. Not sure about how they're characterizing the Mule though, he's not supposed to be some superman blasting his way through the galaxy, but the man in the shadows, orchestrating everything from behind the scenes.
