What I liked:
-The episodes in the middle. Some of the storylines were delved into more deeply and I really began to care about the characters.
-The friendships. The show started with each character being sort of an island unto themselves. They didn't care about one another, there were a lot of people being mean to each other. I liked how the show focused on one specific character and showed how the others came alongside that person to help them.
-A special teacher that cared about the students and helped them.

What I didn't like:
-I almost dropped this show early on because the FL was such a mess.
-The irrational storyline. The ML doesn't go to college and stays another year in high school, why? His father, I'm sure, had to pay for his schooling, yet he had no idea what his son was doing?
-The unprofessional, bullying teachers and administrators.
-The kids live at school, and it keeps getting drilled into us how much time they have to spend studying. They'd have more time for schoolwork if they didn't have to clean the classrooms/hallways, sweep the sidewalks, and handwash their clothes in the sink. Oh, and eating standing up?
-Unnecessary rival shows up for a few episodes.
-There were so many characters, and some of the storylines were never fully fleshed out.
-Abrupt, 10-year time jump
-THE ENDING, my gosh the ending!!!! I know that the romance was secondary, but the ending broke my romance-loving heart.
