I can't say I liked this. It was too sentimental and dramatic for my tastes, and that's saying something considering how much of a serious guy I am. I guess I didn't think that a show based on humor deserved such a melodramatic endcap.
Well, remember...the WB! had undergone new management and thus, even though this film did have its Disney-esque sentimental moments (Dot "dying"), it did still have some of that old A! sparkle, namely thanks to Rob, Jess, Tress, and the rest A! cast trying to rekindle that classic magic.
I just saw this movie on Cartoon Network recently, and I loved it! Just about all of the Animaniacs characters can be seen in it as well as most of their original voice actors doing the voices of them (including Julie Brown as Minerva Mink)!
