SEASON FINALE: This series, a prequel and intermediate variant to the familiar Batman story from DC Comics, has been all about reinvention and new identities, many of them dramatic. Characters, over time on this series, have morphed into the Riddler, come very close to familiar alter egos as Poison Ivy and Catwoman, taken on more of the attributes and attitudes of the Penguin, and even stepped closer to the dark vengefulness of Batman himself. Two weeks ago, Morena Baccarin’s Lee, who started the series as a co-worker of Ben McKenzie’s James Gordon, then worked through the roles of Gordon’s lover, followed by becoming the wife and widow of another man, just injected herself with a serum to turn herself unusually strong and emotionally evil (pictured). She is, in essence, the show’s newest villain – except, at the end of last week’s episode, Gordon did the same thing. There are very few good guys left in Gotham right now… and all the various villains, in tonight’s two-hour season finale, are fighting furiously for turf.
