If you like Cory Michael Smith as The Riddler (and he IS the best thing in it), then check out the new film 1985, it's a Christmas AIDS drama (!) he takes the lead in and he's excellent. Proves he has some range and can play somebody relatively normal just as well as he plays a maniac.
So long, Gotham, it's been... well, it's been nuts really. They managed a variation on different levels of hysteria from episode to episode, scene to scene, but it's never been boring and they've obviously had a ball playing with the Batman rogue's gallery - we even had The Ventriloquist before the end (briefly). I do note they never said the name "Batman", not even at the last line when we expected it! Anyway, Batman always had the best baddies in comicdom, and they exploited that. I don't know if I'll miss it, but I did stick with it, which is more than I can say for some superhero TV shows.
