Some Justice League Unlimited fans are still coping with the series coming to an end. And finding new DCU shows to follow hasn't been easy, but it's been getting better. Legion of Superheroes is heavily underrated and, believe it or not, The Batman has actually improved leaps and bounds over the really crappy first few seasons.
I will say that it goes in a different direction than any other Spider-Man show. Whether that's a good thing or not is up to you. I wasn't all that keen on it, myself. When did Spidey ever run afoul of the Frightful Four...ever?
