SPOILERS
Terrible. It is so ridiculous as to be laughable. The story is disjointed and all over the place. A female Robin comes out of nowhere, walks in to the story out of nowhere, and we're supposed to just accept it. Oh, and she knows how to fly helicopters and drive tanks somehow. The voice acting is all wrong, the joker has no style and doesn't even have joker vibes. On top of that salad of stupid, President Reagan (no kidding) decides he wants batman dead because he saved a city, on horseback no less, and superman just says, "okay, I'll kill him."
Batman then beats superman up, dies of a heart attack, Alfred has a stroke, the manor burns down, and then it turns out batman didn't die. No, he lived and he decided to lead of a gang of mutants he had previously assumed command of to fight crime in his stead based out of a cave..., somewhere.
Honestly, it is one of the most idiotic, absurd cinematic debacles I've ever born witness to, and yet, somehow, it enjoys very high ratings.
I cannot, for the life of me, comprehend what people see in this production.
