The storylines are actually based on stories written by the original comic book creators, which has led to quite a bit of fan support. Season one focuses on the creation of the Avengers due to a mass breakout of super villains from all of Earth's most dangerous prisons.

As the series progresses, new characters and villains show up to expand the universe. Familiar characters such as Spider-Man and Captain America make an appearance alongside relatively unknowns such as Vision and Hawkeye. Recurring villains include Loki, the Enchantress, the Skrulls, and the Kree. Cameos include characters from many of Marvel's other properties, which has helped to keep the fans happy. These cameos have included Wolverine, Doctor Doom, and the Fantastic Four.

Much of the series praise has come about due to how true the creators have remained to the source material. The source material was written by Stan Lee, Jack Kirby, and many other writers.

In the end, this series has received almost universally positive reviews. There has been some concern that the series had been cancelled, but this has been debunked by the creators. The series will return as the Avengers Assemble television show set to premier in 2013.
