Let's be honest, any show will live or die based on how good the characters are, how good the actors are, how complicated the relationships are, how grounded they are and how much heart they have.
Eric KripkeIf I had a worldview, and I don't know if I do, but if I did, it's one that's intensely humanistic. [That worldview] is that the only thing that matters is family and personal connection, and that's the only thing that gives life meaning. Religion and gods and beliefs - for me, it all comes down to your brother. And your brother might be the brother in your family, or it might be the guy next to you in the foxhole, it's about human connections.
