I do wonder how they're going to handle a Superman series in the Supergirl continuity. I mean, this is a world where Superman has been around for a couple of decades, yet has never battled most of his traditional villains aside from Luthor and Zod, since most of the Superman villains we've gotten were introduced as adversaries unique to Supergirl. Yet at the same time, it's a setting that should be a dozen or so years beyond the traditional Daily Planet situation, since both Cat Grant and Jimmy Olsen have done their time at the Planet and moved on to become media moguls in their own right. So this is a Superman who has been around a lot longer than most screen Supermen, but faced far fewer recognizable foes in that time than any since George Reeves. What's he been doing all that time? And who will he face in his own show, with so many of the core villains already used up by Supergirl?
Well, hopefully we'll get Jon Cryer's Lex as a recurring presence. Even though he and Superman-38 are both in Crisis, we haven't gotten to see them play off each other much.
