I think Megamind works the same way, How To Train Your Dragon Works. The story maybe be cliche but it's the characters and what they do with them that draws you in. Granted, Megamind doesn't beat HTTYD, but it's still awesome! Just proves that characters are just important as the story itself.

(With that said, am I the only person wondering what Roxanne and Megamind's kids would look like? I'm thinking blue skin children. XD)
