I did the same thing. I didn't watch The Walking Dead when it first started because the zombie-genre wasn't really my thing (or my husband's). Well, we were bored one summer weekend, and Netflix had the first season of The Walking Dead available, so I asked him if he wanted to watch it. I got this look, like, "okay, she has finally gone completely around the bend". But, I convinced him that I had read great reviews, and people seemed to like it; and, anyway, if we really don't like it, we can turn it off and never watch it again.
He sighed and said, okay --- and, we got hooked. It is now one of the few shows we look forward to every week. Same with Breaking Bad. I really wasn't interested in this show because of the subject matter; but, we both like Bryan Cranston (my husband is of the opinion that he will do anything for his "craft"). So, Netflix again, and, again, we are hooked.
AMC really is putting out some good stuff. Interesting stuff; but, adult stuff.
I think it says a lot about how AMC puts shows together that the big “note” the Walking Dead guys got when they submitted the script for the first episode was “slow down”, they want characters to breath and grow, they aren’t looking for fast cycles of big reveals and scares, they want the audience to get to know them before killing them (how about that second season finale of Hell on Wheels, woh). I’m surprised your husband still like Walter White, the goal of the story arc is to finish the show with him hated, he’s gotten pretty unlikable at this point.
