I'm really sorry to inject reality in here but --
Do not expect profundity from movies. Movies are the ultimate distillation: 90 minutes of action, with very little in-depth dialogue supported, which means every ideal of the story must be super-simplified into a partial truth.
Movies and TV are good for the same things pulp novels were: mysteries, violence, adventure, big-breasted women and men with six-packs, gunfights and explosions.
They are not good for any kind of truth, which requires a more in-depth look only afforded (barely) by a novel or (more substantially) by non-fiction writing.
Movies are how they keep the proles occupied so they don't burn down Oakland every week.
Do not fall into the modern trap by taking information from movies, music or TV as "reliable" -- see it for what it is: symbolic entertainment. It is not reality. It does not describe reality. In fact, it is the opposite. It is alternate reality for those who find reality too painful because they're stupid losers.
