They had a solid idea for a drama but they were totally clueless for how to fit it into a 16 episodes mold. The trolley dilemma was a poor idea to implement in the drama. They were afraid that the viewers may not notice so they went ahead to explain the trolley dilemma multiple times. The FL's kid was learning about it with visuals in school. Kinda insulting. Its finale execution of this analogy turned out to be disappointing and bland, especially after shoving it in our faces endlessly and having the drama named after it. Anyway, the drama was plagued by narrative and writing problems, especially with its horrible and dysfunctional characterization.
