What would you have liked to have seen more of on this series?

* More Riddler - this show did a great job of redefining a lot of characters, but the Riddler episodes aren't the strongest. His motivation was pretty weak, his episodes were more dated (video games! Kids LOVE video games!), and he just wasn't very interesting at a dramatic level.

* Better Penguin episodes - Some of his appearances can be quite amusing when he isn't the main villain like in Almost Got Im or the Strange Secret of Bruce Wayne, but of the episodes where he's the central antagonist, the only one where you really get a sense of the character is Birds of a Feather. Most of his episodes, he feels like the villain just because they needed to choose somebody for that episodes.

* More Mr. Freeze - Heart of Ice is a masterpiece episode that redefined the character permanently, but I noticed most Freeze stories I've read or seen are just retellings of Heart of Ice and don't take the character in further directions. A couple more episodes following up on Heart of Ice would've been great

* Black Mask - At this point, Black Mask was in the comics. He was not very popular or well defined, but there was an interesting idea for a villain there. A Batman villain who personally hated Bruce Wayne more than other villains hate Batman. However, most versions of the character now drop that aspect of the character, and just turn him into a generic psychopathic crime lord. If the animated series had taken the original idea of the character and expanded upon it, Black Mask might actually be cool now.

* More police episodes - I think POV and a Bullet for Bullock are two very underrated episodes. It doesn't have to be Gotham Central, but maybe give the cops of Gotham more attention. Particularly Renee Montoya.

* More Batgirl - She just isn't in enough episodes.
