I'm probably the biggest sucker for these animated superhero films out there, but this thing is profoundly unenjoyable. There's not a character who's integrity remains intact come the end of this thing, as the film shits all over fan favorites like Batman, Nightwing, Harley Quinn and Poison Ivy. The idea of making something of a comedy collaboration between the grim, brooding Batman and the sociopathic, fun-loving Harley Quinn isn't an inherently bad idea, but the writing here is just so bad. There's a highly unusual and nonsensical sexual encounter, a few all-time-bad flatulence jokes and an out of nowhere musical number piled onto an already uninteresting plot, with a real bland depiction of a fan-favorite villain. Crude, uninteresting and supremely awkward; Batman and Harley Quinn fundamentally misunderstands the characters it's "playing" with. Still refusing to believe that was actually Nightwing.
