Still not finding Rogal Zhar all that interesting, and I can't say I am a fan of Superman being replaced by his son as the focus of the LSH, either.
It's strange. Action Comics is sooooo good. There's a lot of good stuff in Superman--I mean, you can't go wrong with Ivan Reis on art--but there's a lot of stuff that just has me scratching my head trying to figure out what Bendis is going for here.
