You'll be happy to know that there aren't many spoilers to spoil. I read the comics after the premiere and Kirkman hasn't made any big reveals yet so really, I just have more questions. It's one of the reasons I'm so surprised that they went ahead with the show, they'll be heading into unknown territory once they get to Season 2.
Oh, I love it. This show is like a Shakespearean tragedy. The Reverend's life is a lie, the protagonist is suffering immensely because of a force he can't tell anyone about, the only way to stop them is to "beat the demon" out of them (made worse by him having to beat children and women), and if he told the person he cares about the most, someone who may even believe him, she would hate herself.
This is seriously one of the best new shows of 2016 and deserves so much more attention.
