I think it's worth watching at least a few episodes, especially if they contain the Joker.
There's a couple of definitive episodes that need to be watched.
The Animated Series
-Laughing Fish
-Almost got 'im
-Feet of Clay
-Robins Reckoning
-The man who killed Batman
-Heart of Ice (this is the episode that won the show and an Emmy)
New Adventures of Batman
-Old Wounds
-Over the Edge
-Mad Love (the best episode of the lot in my opinion)
I've never watch Batman Beyond (it's on my to do list) but the movie Return of the Joker is damn good, especially for the one section set during the original Batman.
