I have no experience with the source material I had never even heard of it until the show was greenlit. So I don't have any pre conceptions on what the show *should* be. That said, I enjoy it. I too am patient and am comfortable waiting for them to start explaining stuff. And slowly but surely, they are. After Episode 5, I've got a pretty good grasp on the characters and the general premise.
It's holding my interest. It's funny, irreverent and suspenseful. I certainly didn't expect what happened to Eugene at the end of episode 5. The only thing I'm not sure about is the cowboy in the flashbacks. I'm not sure how that ties in to the main narrative.
