It's wonderful. I was afraid early on that it would be little more than a buddy-cop / odd-couple show, but it avoided that trap and has really been a pleasant surprise with solid character development and a compelling story arc. I can hardly wait for the next season.
I know it's probably hilarious, but I'm SO over shows being "clever" by using religious references, angels, devils, heaven, hell, etc.. I don't want to see any takes on silly religious myths, unless they are Greek myths, which I do find entertaining. I suppose people who take religious beliefs seriously like such shows, but I don't.
I've seen previews, and forgot to check it out. What channel is it on?
