Yeah it's a slow show and I don't think that's doing it any favors. We're 9 hours in now, which is a long time for simply a setup. They're lucky that the actors are so enjoyable, and that DeBlanc and Fiore are such great characters as I don't think the main trio could keep you watching 9 hours for the story to get started.
I read a theory that DeBlanc and Fiore are the parents of Genesis. Seeing as one is a demon and one is an angel based on their dialogue this week that seems a safe bet. Good move elevating them as characters.
I still love the way you have no idea what's going to happen in this show, and it's clear they have a plan, but I do hope things pick up a little. I'm hoping AMC ony gave them budget for a first season in this town, it's beginning to feel like season 2 of Walking Dead. I'm not sure if the ratings are high enough to free up the budget to really make the series sing, so I'm thinking it's going to be a little frustrating for the entire run.
