This was truly interesting and one can see the repressed rebellion and suppressed emotions of teeners. The lad, in his solitary moments become an imaginary monster who destroys cities as a way to burst out his discouragement over the bullying that he experiences. Add to that his feelings for a girl that he just can't express. The concluding scene shows him again in an imaginary setting destroying everything in sight and this happens while he sends a message to the girl on the phone, which was actually received by the girl. Great musical scoring, the animation that connotes disarray and he realness of the characters all contributed to the charm of this film.
