I re-watched it not too long ago and it just didn't hold up for me at all. I watched the hell out of this and Returns when I was a kid and I loved them...hell I even liked the Schumacher ones when I was young. I still liked the 80's feel and the art-deco feel of the city. The Batman costume just looks ridiculous and I could see Nicholson's mouth inside the makeup mouth every scene you see him. It's still a great movie, but having seen many many movies since then it just wasn't as good as I remembered. The Animated series from the 90's holds up much much better and it's my favorite Batman media that isn't the comics.
I feel like this only looks so bad because this was a poorly put together trailer. I wonder if this is all of the finished footage they had from the editing room. I'm still pretty excited despite this terribly put together trailer.
