I think Elementary was the *only* survivor from 2012 (OTA) in my SPs. That makes it the best.
Was Arrow new last year? If so, it was the only other 2012 show to make it. Revolution lasted about 2/3 season before I pulled the plug.
I think there were a few cable shows, but I'm not in front of my TiVo to look them up.
Edit: Just found out FutonCritic lists start dates for shows. Three OTA shows made it last season (for me): The Neighbors, Arrow, Elementary. I'll stick with Elementary as my fave.
