Forget about the comics the Batman: The Animated series cartoons and Batman Beyond were both so freaking awesome. Maybe this is simply my childhood talking but there are some of the most interesting take of the tragic villain archetype ever showing were in the Batman: The Animated series. They portrayed as wrong and evil but you could feel sympathy for them. Some of them, there was also the most awesome Joker ever who was clearly ever and Harley Quinn. Batman Beyond has cyber punk at a rating level I could actual watch and old Bruce is probably my favorite bitter old man mentors ever. In the opening he actual considers letting Terry (the kid who stole the bat suit) die. Then there is ace the bat dog.

Congratulations for your grandfather and have fun yourself.
