The first point is that the trap for the male protagonist cannot stand logical scrutiny. The killer of the other party's gang is not enough to identify the protagonist as the second-generation black son with just one sentence. The expressiveness of a movie does not absolutely depend on the scrutiny of the plot logic and the realism of the shaping, but a plot that is too unreasonable will make people lose the sense of realism and weaken the expressiveness.
The second point is the plot of the second black generation stealing the child in the end. The first half of the film has already described the various mistrust of the gang boss to his son. However, the final task of killing the child was easily handed over to his son. This scenario is too wishful thinking.
