High School Musical Syndrome

When the main character in a production (Mostly Disney) that appears on either television or film such is normal in the beginning, shallow in the middle, and becomes normal again in the end, realizing what a total dick it was. I just call it HSM syndrome because it's one of the most obvious film you would see it in.
Troy Bolton in HSM 2

Jo in Mean Girls 2

Kady in Mean Girls

They are all clear examples of High School Musical Syndrome. If you don't believe me look it up for yourselves.
