SR was OK. Not great, but not terrible. Casting Routh as CK/Supes was a good move because of his physical resemblance to Reeve, but his acting chops are ... limited.
even played on the resemblance in one episode that mirrors a scene from a Reeve movie.
The thing that killed the Routh portrayal for me is the eyes. He has dark, black, dead looking eyes. There's no smile in there.
