Totally agree, the DCAU voice acting is top-notch! Kevin Conroy and Mark Hamill are the dream team, for sure. Their dynamic in "The New Batman Adventures" is a highlight, especially in episodes like "Mad Love," where you really feel the layers to their characters. I’ve always thought Ron Perlman’s Clayface was underrated too; his ability to convey that tragic struggle is just fantastic.
Andrea Romano deserves a ton of credit for her casting choices, it's no wonder the DCAU has such a lasting legacy. For me, one of the standout performances has to be Susan Eisenberg as Wonder Woman, she brings such strength and depth to the character, especially in "Justice League" episodes like "The Brave and the Bold."
Do you have a favorite episode where the voice acting really hit you? I always find myself revisiting "Heart of Ice" for its emotional weight!
