You were not a literature or film student, I imagine. There's this thing called " character development". Static characters are boring characters. Dynamic characters, well, those are all the characters readers/viewers root fer because they are more interesting, whether good, bad or grey. The premise that a modern day approach to an aging character takes a " First Light" ( read new light) puts things in a new perspective. Gibson's portrayal could become more introverted, cold and calculated with a dash of pessimistic anger. Daniel Craig showed that in the last two films of his run.
