We all know High School Musical. The 2000s was the peak of Disney Channel (I am taking no further comment on this), and High School Musical was one of the reasons.

An iconic movie, with iconic characters, but that doesn't mean I liked them all.
I find him annoying, and let's be honest, he was a jerk for the most part of High School Musical 2. However, while it was definitely on the cringe side, "Bet On It" was a bop, so points for that I guess?
Gabriella was totally unrealistic, and portrayed as a Mary Sue. Also, I find it weird that it was her first year at East High, and suddenly she became the most popular girl there.
I liked her character's personality but I think she should have had more of a storyline as well. To me it felt like she idolized Gabriella and Troy, which I didn't really like that much. Also her relationship with Ryan was so forced lmao.
Ryan was such an underrated character, and imo should have gotten more screen time. He's just fun and a good character overall so I would rank him in second place.
Sharpay Evans is hands down, my favorite character in High School Musical. I love her and everything about her, from her ambition, fashion, and vocals. She actually worked hard in theatre, unlike others, but never got the proper recognition she deserved.
