As well you should while wearing that avatar and name Dacon, you hit the nail on the head with regards to the DCAU. Its one of the big reasons I love it, its direct translation of many of the characters most important characteristics and the way in which the stories play out. Batman's paranoia, Hawkgirl's sublimation of her emotions with a big honking mace, etc. Plus props to them for using John Stewart as the Green Lantern for a change.
And I loved how they managed to toss in some humor in unexpected places. You expect the Flash to be funny and zany, that's part of his natural appeal. But Superman promising to pay for Luger's shiny new city he had wrecked beating the stuffing out o poor Captain Marvel, then thinking twice and looking over at Bats (being as he's the poor sap who has to pay for everything) and getting that really pissy nod in return? That's awesome. Plus they managed to sneak in a reference to Martian Manhunter's love of Oreos in the Christmas episode. And of course, Mark Hamil is the best Joker ever. EVER. Not to take anything away from Heath Ledger, he was awesome with his variation on the character, but Mark Hamil will always be Joker #1 for me. Shit, I'm all nostalgic now, I may disappear for a while to watch old Batman TAS and Justice League episodes.
More on topic, didn't we have the Riddler on in the last Batman film franchise? Must we do that again so soon? Batman Begins gave me high hopes, with Rahs Al Ghul (even if he was Liam Nieson, it worked out ok for me) and Scarecrow, villains that hadn't been in the Tim Burton-originated series. And of course TDK had the Joker, you cannot have a Batman franchise without the clown showing up, it'd just be wrong to leave him out. And TDK gave us a Two-Face so vastly superior to Tommy Lee Jones' version that it gave me nerdgasms. But really, we're back to the Riddler? I mean, so long as he's not Jim Carrey this time and is semi-well written it could have potential I guess, Riddler is a good character if somewhat limited. But if we have to see a villain we've already seen in a prior Batman movie, I'd like to see Bane again. Bane done right, brilliant, self-taught in nearly any subject you can name while he was in prison, tactically sound, broke Batman's fucking BACK Bane. Of everything I hated about Batman and Robin, and I hated a lot in that movie, Bane pissed me off the most. Gimme a corrected version of Bane over the Riddler any day.
I wouldn't mind an appearance by Killer Croc either, poor sap gets so neglected. Or Clock King, going back to Batman TAS, Clock King was fucking awesome. They may not be headline villain material for a full length motion picture, but seriously. Joker, Two-Face, and Riddler get all the love.
Also, if its gonna be the last one in the present series, I say we connect it firmly to the opening salvo that was Batman Begins: Tahlia Al Ghul ftw!
