The Joker and Lex Luthor team up to kill Superman. Bruce Wayne is visiting Metropolis to make a business deal with Luthor. In the mean time, Wayne starts dating Lois Lane. Superman and Batman join forces to take out the Joker and Luthor.
Pretty standard cartoon comic book movie. I enjoyed it. Really fast paced and good action scenes. It was good to see Harley Quinn. I like her comic books but have never seen her in Batman: The Animated Series. Lois dating Bruce Wayne was interesting. She saves Batman at one point while he's fighting a robot and sees him without his mask. She ends up not really digging Wayne being Batman and they go their seperated ways. Good story.

8/10
