I stopped caring about Bale's Batman jaw years ago. While I recognize that he doesn't have it, an angular look works for the character, who is all sharp edges and whatnot.
I can't figure out who the hell decided jigsaw legs made any sense. Why would the armour be designed like that? It's completely beyond rational explanation. The rest of the suit, despite the fact that it's not Batman, makes some degree of fictional sense, but the legs? What the hell? The pattern doesn't even conform to muscle groups. It doesn't conform to anything. It has no purpose, practically or aesthetically. It doesn't look like armour, it doesn't look realistic, it doesn't represent anatomy, and it doesn't look like Batman--it doesn't serve any goal the costumers could have possibly had. It's just visual diarrhea.
Pretty much.
Perhaps it's designed as some sort of armored material, but is broken down to give Batman more freedom? While at the same time, it's broken down in a way to look remotely methodical.
Trust me, I'm not a fan of this suit -- the head is bloody stupid -- but instead of sitting here, saying "WHY, WHY, WHY, WHY", why don't we try to understand the thinking behind this thing?
I'm not so sure. I mean, it's free at the groins; it's free at the knee-caps; and I assume all of the other breaks are designed to create even more flexibility for the Batman. Sure, there are a few random pieces laying around, but I think that's solely to create as much flexibility as possible, all while maintaining a relatively "cool-looking" and "professional" appearance.
We've tried that line of thinking. There is no rational thinking behind that. The human leg does not need to move in those areas in order to have mobility.
Segmentation at random areas does not create mobility--segmentation at areas where there is stress or buckling creates mobility. That's not what they've done. Those criteria are met, yes, but then they've added a dozen other superfluous breaks that serve no purpose. After you've made the necessary segmentation, cutting a subway map into his leg isn't going to make it any more mobile than that.
And that's about the long and the short of it. If they went so far as to explain this as neccessary for mobility, then their logic is faulty, and the suit and Batman's visuals suffers for it.
It is what it is. An overdesigned techy suit that could have been much, much more appropriate for the character.
I will never understand why the neck has to look so "involved". He looks like he's wearing some kind of a dog collar now. Clearly whoever designed this element of the costume has no idea what ventilation is actually needed in wearing such things. You don't need neck ventilation, you need HEAD ventilation. For instance, the ears could have had some kind of subtle "ventilation" added to them. That would have increased the actors comfort and looked kind of "batlike".
The bat-emblem on the chest now looks like someone smashed it with a mallet, leading to that ugly "gap" between the pec armor.
The shoulders and arms are what they are. The pads are a bit too involved looking, with random lines and "raised" areas, but ok.
I will never understand why his pecs are multi-colored, lined, and "layered". The ab stuff is overdesigned, with all the little lines and so forth cut into it, but I can live with it.
The legs are simply AWFUL looking. And I really have yet to meet someone who says otherwise. Everyone seems to recognize that they serve no practical purpose, so why didn't a TEAM OF PROFESSIONAL COSTUME DESIGNERS? Now, they've obviously designed the legs so that you can see the mesh underneath, so that the entire suit has some of the "mesh appeal". But it looks awful. The mesh isn't a cool enough or visually interesting enough concept to RAPE THE BATSUIT.
Overall, the design simply distracts in every element. Each overdesigned element, and there are a lot of them, distracts from the main elements of the suit. And that, to me, is not a good design. As for the gray...I get that they went "Batman is gray and black, let's bring some of that into it", but the juxtaposition of the colors simply doesn't work well enough to warrant that approach.
