It's alright. Certainly better than most comic book shows. Probably my third favorite, behind Daredevil & Jessica Jones (I can't even force myself to watch Gotham, Supergirl or the CW shows).
I think a 6/10 is about right, and the only reason why I even rate it that high is because they cast such a good lead. Never heard of Tom Ellis before, but he's a lot of fun to watch. I really hate that they turned it into a police procedural, though. I also wish they'd play up the supernatural elements more.
