Mission thanksgiving. The turkeys time to fight back!
It is definitely an underrated animation. Okay, I agree, Disney is solely dominating the animation industry, especially at present. But this film is no masterpiece like that Disney makes yet not bad to ignore complete. Yes, there are flaws in it, but very acceptable as they're just minors. In the animations, the real world logics won't apply. So you should try to enjoy it than trying to find the errors.
This film is targeted for children, but then anybody can watch it because it is a beautiful theme with some real laughs in it, only if you forget that you are an adult for a 90 minute. Technically the film quality matches with Disney, Pixer, Dreamworks and even the Sony animation....
