Is there an animê series/movie you think is underrated?

I honestly think that the Rosario + Vampire animê and Digimon: The Movie are underrated.

Most fãs of the R+V mangá often dismiss the animê as terrible, and I honestly don't know why. The only problem with the animê is that there weren't enough episodes (they probably could've made mais than 12 episodes).

I honestly don't know why the Digimon movie was hated por critics. The animation was fluent, the voice atuação wasn't half bad, and the action was awesome. And let's not forget the kickass soundtrack.
