This is a bad show produced by Marvel, a big wrong move was made.
Plot: The characters from The Avengers, and other heroes from Marvel ( Iron Man, Hulk, Wolverine, Thor, Falcon, Silver Surfer, and Scarlet Witch) are the ones that protects the city named, Hero Town. They need to stop Dr. Von Doom to complete the shards of the "Infinity Sword". It's a great plot actually, but the mistake is kiddish, they named it Hero Town. They should have named it better.
Characters: The characters act kiddish, and this lessens the action value a lot.
Action Value: Due to its childish orientation, it has a very few value.
Art: Also, they mistaken the art, the characters are very small, they should have sized it a little more than that. Animation is a little poor.
Overall: 3. Marvel made a wrong move here, they should put this show back to the closet and Focus on the real Avengers cartoon.
