I'm using "lesson" as "underlaying value of the story", not necessarily that I agree with that or it is used in a conscious way, but it's the way it is presented... "someone has problem, someone uses violence, the problem is fixed and everyone is happy!" (Again, I don't think is a huge deal and I am not implying that people can't distinguish fiction of real life or something)
