This entire game is carried by Komaeda. I dislike half of the cast and only like about 3 characters total, counting him. Komaeda is a very cool character but this game uses him as a crutch for its dramatic tension. Unlike DR1, there's no real "beat the mastermind" thing going on behind the scenes. You're just existing until either Monokuma or Komaeda stirs enough shit for someone to get killed. There's no agency. The ending is a cool twist but the protag yelling the same words at an AI until he wins isn't a very satisfying ending, especially considering that it essentially means the entire plot of DR2 feels like it was meaningless from the beginning.
The only reason this isn't a 0 is because Komaeda is in the game and 2-5 is the best case in the entire series
