Rane Peerson’s review published on Letterboxd:
What does it say about the source material when my favorite part of the film was the taped-on Batgirl prologue, pointless sex scene and all? And even that would've made for a subpar BATMAN: THE ANIMATED SERIES episode at best. It was fun to hear Mark Hamill's Joker again, and maybe Brian Bolland's artwork adds something that the adaptation can't capture, but frankly I just don't understand the appeal of this story. Joker's depraved theories on the concept and causes of insanity bear the mark of a first-year Psych student's "edgy" theorizing, and providing both a backstory and an explanation of Joker's psychology almost ruins the appeal of the character. I'll take the unexplainable, gleeful agent of chaos and mayhem over this bad joke of a sympathetic villain any day.
