This show is excellent entertainment suitable and aimed for kids. It pairs one of the most popular and greatest superheroes of all-time with some un-recognized (but good) B or even C level Superheroes that never get much attention. While I like Tim Burton's Batman, love Batman: The Animated Series and love Nolan's Batman, This is not dark, gritty, and doesn't have an amazing awe-inspiring story, but it's it not trying to. This is not the tragic, mob-boss/realistic villain fighting, detective Batman. This is a lighter but not ridiculous (Batman & Robin), superhero Batman. The animation is different than other prior DC Comics cartoon, but it's good, smooth animation.
So, If you want something dark, gritty, and thought provoking like The Dark Knight or Batman The Animated Series? Go watch TDK or TAS. This is entertainment, and some good entertainment at that. I would rather have good, pure entertainment than a failed attempt at another dark Batman.
Fanboys need get over it and stop being whiny baby-men. Remember, there's always that off button on the remote.
That's all I've got to say about that.
