The serie is based on the same idea as Wolverine and the X-men, which is normal as they are spin-offs of each others (they are based in the same universe, and they refers to each other a bit). The same graphic style was selected, but contrary to wolverine and the x-men, in which it was too rough, they improved here and it was pleasant.
Based on a what if with Iron man as team leader, characters pulled from different incarnations of the team like her sister serie, the stories are better than for wolverine and the general plot better supported. It suffers the same flaw of bringing too many characters in the episodes, but since they are villains who often are just background to the real plot it is better than the other way around did for the X-men. The decision of having Giant Man a pacifist was also a real change from what I remember of him, and a really good thing.
BTW, I would like the serie's theme song but I can't find it...
