Is there an anime series/movie tu think is underrated?

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

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

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