Joe, a red-headed movie buff, and Silvia, his girlfriend, are having a bit of relationship trouble. Silvia feels that Joe is taking her for-granted and wants to do something together for once, so Joe decides to take her to see an old action movie featuring his favorite hero, Captain Blue. What started out as a cute movie date takes a turn for the worst when Silvia is pulled into the movie by the leader of the evil organization, Jado.
Joe follows her into the mysterious "Movieland," and is granted a powerful device known as a V-Watch by Captain Blue himself. With it, he transforms into the action hero named "Viewtiful Joe" and goes off to rescue his girlfriend before she can be used by Jado to take over the world. It's a long road to go from average Joe to full-blown hero, but he'll give it his all to save both his girl and the world—and he'll do it in the most "view-ti-ful" way possible.
The anime as a whole is more or less true to the game it was based off, most people regard it as an anime/children's cartoon and this is true in some regards, I liked the anime out of sentimental reasons and because the morals were just out there having to deal with life and being a hero, you get to the point where you root for Joe and get a laugh or two but also realize that he's just a dude trying to rescue his girl with his own twist.
Henshin a go go baby! Transformation is a staple in many genres of anime, from fighting to magical girl. The sacred rule of transformation is that no other character is allowed is interrupt while you power up to your next form, so of course you want to make things spiffy with a henshin sequence.
