I don't require that I root for the protagonist. I don't much root for Jessica Jones, but she has enough going for her and there are interesting characters around her. But if you're going to tell a particular character's story and all that character does is repel the viewer, what's the point?

As for Walter White, what is he proud of? What is he defending with his lies? As I said it's not just the lying, it's that I don't see the motivation for it. Like, sure, I totally get that you don't tell your straight spouse that you're cooking meth. But I don't get why he dislikes her so much, and yet has been with her for this long and they're having another kid? I don't mind if characters are dislikeable, so long as I can grasp their motives. I'm writing my review in another window for Altered Carbon S1 and in that series the main character's sister (Reileen Kawahara, played amazingly well by Dichen Lachman) is really f'ing bad. But I get why. I don't _agree_ but I see what drives her to do what she does and it's consistent.

As for Black Mirror I think it's hilarious that everyone agrees that I watched the wrong ones (S1:E1 and S5:E1) and if I just watched these OTHER ones (on which nobody agrees) I'd see it differently.
