While Brave Citizen is not necessarily revenge based, Ballerina is. However, the reason why I consider both movies to be similar is because of the action scenes and badass female leads. If you liked that aspect of Brave Citizen, definitely try Ballerina.
Both are revenge based. If you liked the action scenes in The Manipulated, you’d be more than happy to witness the ones in Mercy for None. The fighting scenes in it are just impeccable.
Undercover High School’s storyline is not mainly based on seeking revenge or beating up bullies. However, it’s still something that Teach You a Lesson fans would find very enjoyable as the protagonist of the drama is a cop as well and puts bullies in their place even when that’s not a part of his mission. He exposes the school he’s undercover at and also its principal(the antagonist), indirectly seeking revenge for his father. Moreover, actress Jin Ki Joo is a part of this drama as well!
Both are set in a scenario based on seeking revenge for other people. While Teach You a Lesson is solely related to schools, teachers, students and anything along the lines of that, Taxi Driver captures broader areas. Definitely try Taxi Driver if you want to watch a more inclusive version of Teach You a Lesson!
Pretty similar, imo. Both are predominantly revenge based. I believe the fighting scenes are quite alike as well. However, The Manipulated may be a little more on the extreme side. It’s still worth the try
