I checked out both Arrow and Nashville, and enjoyed them both, although I'm not sure if either will continue to be must watch for me. Arrow seemed like a meld between Hamlet and Batman - didn't think it broke any new ground in the comic book genre, but I was entertained. I just wish there had been more humor. Or, any humor. I watched Nashville for Connie Britton, and she did not disappoint. I'm not really a fan of soap operas though, so the genre was working against it. I'll watch a few more times though - I liked the music storylines better than the family/political ones.
