Joel Schumacher's obsession with smoke and lights...
It's noticeable in a lot of his movies but it's truly irritating in this one. Almost every scene has either one or some combination of the following: flashing strobes/lights, neon lights, totally not subtle smoke machines, that effect that looks like the reflection of water on the walls even when there is no water anywhere, gel-covered lights, and in most of the scenes it makes no sense to even have these things.
I am fully aware that some of it has a meaning or symbolism but certainly not all of it. It's like being visually accosted for an hour and a half. The smoke machines are ridiculous in this movie.
Dick, I am VERY disappointed.
