Such as this: the dawn of Batman Beyond.
I know some folks dismiss the property as Batman-lite (though I know others who've said the same of Nightwing, Catwoman, and a handful of other comic book properties), and that's a shame. The animated 'What if?' extension of Batman: the Animated Series universe remains a personal favorite of mine largely because it truly took some risks with the entire BatUniverse that remains worthy of your time and attention.
If you haven't discovered it, then shame on you. If you have, pop in a DVD today and relive what it was like to see what happened when Bruce Wayne was too old to carry the mantle. See what he did to make certain that the threat of the Bat lived on in Gotham City the way it could. You might be surprised.
