Yeah, it's always a little disappointing when the suits don't look like the comics but I can understand it as long as it makes sense to change it. Hell, I remember when I was a kid and first saw the suit for Batman '89 I was upset, because his suit was all black and not blue and grey like the comics.
but why so much into the "armor" thing? where are the muscles?
I'm actually relieved there's no muscles. I always thought that was pretty lame. I mean really, why would Batman have sculpted rubber muscles on his suit? The world created for Begins is meant to be more realistic and having Batman in armor makes more sense than fake muscles. I always thought it was a way to make up for the lack of physique for the actors who previously played him. Christian Bale is in great shape, so he wouldn't need them anyway.
