Once and for all :
1. Art aiming at recreating life as faithfully as possible is simply missing something about what art is supposed to be!
2. Be it director or scriptwriter(s), someone at some point has to adopt a point of view of the main character - not seldom a forgiving point of view, for obvious reasons - which would be acceptable if it didn't unmistakably lead to a biased portrait.
3. You Cannot Tell A Whole Life-Story In Just Two Hours. Or even three.
You just can't. No way, no how. Not possible.
