Loathe as I am to criticise Shakespeare, I'm not sure this play is really all that well-balanced, although I'm not familiar with the text, so I'm not sure how much of it was adaptation.
There's a lot of fire and huge explosions, as well as quite a few nightmarish hallucinations as the citizens of Gotham are exposed to the Scarecrow's Fear Gas. And along the way, Batman even rescues a young Joffrey Baratheon.
