Animaniacs has always been quite deep for a "children's show" as it was always targeted towards adults as well. With the reboot, I feel the target audience has completely shifted towards adults, or to be more precise, towards the people who were kids during the original show.

Children nowadays can still enjoy it, but they will miss out on most of the jokes and even more importantly they will miss out on the (political) satire which the reboot introduces and which wasn't (really) present in the original. Animaniacs always worked on more than one level and always had a deeper narrative than the one on the surface and with 30 years experience they perfected that art to the point that they can safely address any topic, without the children, the censors, the soccer moms or the PC police even noticing. Which allows them to address issues that any other "children's show" wouldn't dare touch with a ten foot pole and even sprinkle little tiny truths in there that everyone knows, but in today's climate no one dares to say out loud anymore and watching them do that was the most fun for me - but the whole show is just so much fun and just works on so many levels!
