I think that it's an OK series overall. I don't like though that Ben has a hard time figuring out throughout this series the genuine reason for why he should be a hero. I feel like that was a concept that he should have figured out during the first season.I like all of the aliens that Ben gets to be throughout the series. The last episode was random though. I thought that it was weird that he told his classmates and teacher within a very short time about the omnitrix.
