So, tangentially related to costuming: what kind of gadgets do we want to see for Batman, in terms of function, usage, and style?
I would like to see a bunch of gadgets with distinct enough styling that, once properly prompted, the audience can see Device X and know what it is. A batarang isn't just a batarang, but once the audience glimpses an electric batarang, they recognize it even if its not immediately used to shock someone. Etc. No devices that are indifferentiable batarangs or grenades or pellets, and a minimum of singular all-purpose devices.
This is partly because. . . okay, a scene I would like to see happen is "Batman thinks of everything". Specifically, a fusion of the detective lecture reveal and the gearing up montage, where Batman arms himself with a variety of different ( specific ) gadgets, in preparation for an upcoming confrontation. They are identifiable when chosen during the montage, but perhaps vague or inexplicable in usefulness. Over the course of the ensuing conflict, not only do they prove useful in clever and surprising ways, but their use is tied to flashbacks revealing Batman's train of thought, in how he used clues and information from earlier in the movie to make deductions and predictions about people and events later. The result is emphasizing Batman's genius, and how he isn't winning the fights, he already won them the scene before.
Only, correction: there's not one scene like this, there are *two*. The first one goes as above, with everything going according to plan, and the entire conflict revealed as a foregone conclusion because Batman Thinks Of Everything. The *second* one, by contrast, is against the Big Bad, and things don't go nearly as smoothly. Against a foe of comparable genius, unpredictability, or both, and since this is Batman, not Precogman, things are a lot dicier. Not all the plans work, not all the scenarios were expected, and Batman has to improvise by the seat of his pants a lot.
