I think the point Izzy was trying to make was that animals is a theme that will never get old. Since the last pages upon pages of this thread have been about discussing the lasting power of several IPs, it seems worth it to point out that Animal Actors wont ever be outdated with the proper refreshments every so often...the general idea of it wont ever get old. While Dora, Spongebob, My Little Pony, whatever, all may/will become outdated at some point, animals doing tricks will always appeal to people. The fact that it isnt tied to an IP is even better, as there would be no contracts to worry about or anything like that that have also been discussed.
Because of this...that the show has a broad enough appeal and is fun for children and even adults in the right mindset...Im a proponent of leaving Animal Actors. Wanna renovate the theater? Im all for it! But as for the actual show, besides a few minor tweaks I think its in Universal's, and its new family demographic's best interest to keep it. It has a very broad appeal.
