Batsuits :
1 - Batman Begins. I'm a huge fan of the panther neck, and its "puffiness" never bothered me that much.
2 - Batman Returns. Love the armoured look and the cowl of this suit.
3 - The Dark Knight. As far as movies are concerned, I really don't mind the "commando" style Batsuit.
Movies :
1 - Batman Begins / The Dark Knight. Still haven't decided to this day which one was the best. I love Batman Begins as it focuses entirely on Batman, and I love The Dark Knight because it's one hell of a good thriller.
2 - Batman Returns.
3 - Batman Forever.
Bat-actors :
1 - Christian Bale. Only flaw I see in him is the voice, and not because it's too deep or whatever, but because it doesn't sound as natural as Conroy's. I think it still sounds better than Keaton's though.
2 - I'd put Conroy here, but let's be fair, he's only voicing the character, and if I put him there, I would also have to put the animation team who really make his work stand out within the animated series. OK maybe that's what I'll do then. All the guys behind the Batman from BTAS are my second choice.
3 - Val Kilmer. I like his Bruce Wayne. His Batman, not so much, but overall I'd choose him over Keaton any day. The looks are important, and while Keaton could certainly pass as a tortured soul, he looks way too frail and out-of-shape to portray a seasoned crimefighter. And let's be honest, Kilmer did his best to give Schumacher's Batman the most credibility he could. Clooney didn't even try.
Bat-villains :
1 - Joker from TAS (so again, Hamill + the guys who designed his looks + the animation). Only thing I didn't really like about him is that he never was a credible threat. The video game Batman Arkham Asylum fixed that problem, offering us a Joker that looks as good as the one from BTAS, who's voiced by Hamill, but who's also a lot more dangerous, with a higher body count than the BTAS character throughout the whole 4 seasons of the show.
2 - Ledger's Joker.
3 - DeVito's penguin. I really enjoyed his whole arc in Returns, and the performance truly was brilliant.
