Alright, I got one, totally not biased, and completely unopiniated suggestion.
Pokemon: Lucario and the Mystery of Mew.
If that doesn't properly meet the criteria, I have an ACTUALLY unbiased suggestion: The Fantastic Adventures of Unico.
EDIT: Okay, I have some more movies that are guranteed to knock your sock off...for varying reasons.
* Felix the Cat: The Movie

* Felix the Cat: The Movie
* Titanic (as in, the cartoon knock-off. There's two of them, in fact...Not counting the sequel one of said knockoffs has. You'll know them when you see them.)
* Fern Gully 2
* Avatar: The Last Airbender
* Pom Poko
* Bionicle
* Pacific Rim
* Equestria Girls
* Super Mario Bros the Movie
* Nightmare Before Christmas

* A. I.: Artificial Intelligence
* Final Fantasy: the Spirits Within
* The Lego Movie

I apologize if I've suggested too many movies, but I just had so many ideas to mention that it'd be a shame to let them all go to waste.
