The writing can be a little hack, but clearly the animators put a lot of work in. The whole creepy art-deco design of Gotham is really good. Plus there’s lot of cool effects, like Two-Face’s other face being shown in lighting.
I’ve been giving it a re-watch and have been surprised at how good it is.
The DCAU had some really talent people, be Mark Hamill and Kevin Conroy. Or people like Dwayne Mcduffie and Jonh Semper Jr. during the later years.
