This movie reminds me of Harry Potter: somebody with powers that doesn’t know that have them, and goes for a school and finds them. So, the story is kind the same: a super-hero, child of two super-heroes goes for the super-heroes school but, poor boy, he doesn’t have any super powers. Oh well, he has but he didn’t know.
Regarding the movie itself, nice special effects, nice girls, nice jokes, super heroes. So, 8 in 10.
