MegaMan: Wishing upon a Star · review
The Rockman OVA's only issue is that it doesn't last longer. While it has a very simplistic story (your typical "game character comes into reality and they need to stop the game villain" plot), it's executed in an interesting way. They make it educational for a younger audience without pounding it over your head in a boring way. You might even learn something new about Japan when you watch. The characters are all likable enough, and there's a lot of nice interactions between them. I thought it was very sweet when Blues complimented Roll's kimono. It has lots of humorous moments as well. Even the decisionto make Rush talk was done in a cute and silly way, not in an annoying way.
It's just a shame that instead of more of this anime, we got that hideous Ruby Spears Megaman cartoon with a butt-ugly art style and horrible characters that disrespect the source material. Rockman is a series that naturally lends itself to anime adaptations, so hopefully we can see more like Rockman: Hoshi ni Negai wo in the future.
