I can't call this a bad movie, because I'm a sucker for anything with "Animaniacs" in the title. Somehow, the novelty of just seeing all the characters in one place is enjoyable enough for me. Unfortunately, the charm wears off really fast.
The plot holes are gigantic! I know it's Animaniacs, and I shouldn't be asking for logic, but usually things make just a little bit of sense. This movie tries to be a Disney flick, and it's just not working for it. I compaire this story to fanfiction. The characters are out of character, even for them, and for a movie called "Wakko's Wish", Wakko dosn't get a whole lot of screen time. That really makes me mad, because that's my favorite character!
I can't say the movie is terrible; it's decent Animation, the voice acting is pretty good, and even the plot, as cliché'd as it is, is very entertaining. I just fall in love with it every time I see it. It's so bad that it's good. As an Animaniacs fan, I love to pick apart everything that's wrong with it. For an non-Animanics watcher, I'd skip this movie. If you don't know the characters, it won't make much sense, and you'll turn it off before it reaches the ten minute mark.
For little kids, they'll love it. I know I used to. (I bought five copies of the original VHS version when it first came out. One was eaten by the VCR, I lost one, I have two in my video collection, and one is still unopened.) It's a very nice movie for kids, and it keeps them quiet for an hour. Then again, I guess kids love anything animated, so that's not much of an accomplishment.
