Things I think about at 2:35am apparently -
The original High School Musical is the most consistent in terms of plot, characters, and story structure.
High School Musical 2 is the most fun to watch with the best overall soundtrack (even if its existence adds nothing to the overall trilogy).
High School Musical 3 is the most polished with the best production design and the best choreography of the trilogy thanks to a better budget.
All 3 films have their strengths and weaknesses, and honestly??? What an iconic trilogy???? Also, all 3 films pass the Bechdel test and have a diverse cast. Lord of the Rings who?????
