9. Harry Potter And The Half-Blood Prince - Teen Comedy
https://www.youtube.com/watch?v=c_ubmjE21SY The Harry Potter series is certainly aimed at a teen audience, as evidenced by the age of the protagonists and the school setting. In particular, the films take cues from other popular genres for the demographic, with teen romance, comedy and fantasy action filling the majority of screen time. This recut trailer completely forgoes any of the more serious elements in the series, establishing the (relatively dark) Half-Blood Prince as an all-out high school comedy. It flows remarkably well, and it's only the odd broomstick and pointy hat that gives away the fact that it's anything but a raunchy teen hit.
