Animaniacs was certainly ahead of it's time. I don't know about you but I watched this one all the time as a kid. According to Screen Rant, a Steven Spielberg is working on a re-boot of the series with Yakko, Wakko & Dot 3at Warner Brothers & Amblin Television.
At this time, an Animaniacs reboot is still in the early stages so we don't know when it may return. Still, exciting to think that it's coming back!
