i liked the original Batman film, but for me Batman Returns' only redeeming feature was Michelle Pfieffer! still vastly superior to the excrement that followed it though.
as to the "new" films, Christopher Nolan seems to have got it pretty right, although i've never been a fan of the armoured Batsuits. i can see that in real life they'd be a good idea, but they've just never looked right to me. i would think they were first used because Keaton/Clooney/Kilmer didn't have the Batphysique! but Christian Bale does.
