Well, in a 'Mother Father Son' based on true story, themes of identity could be prominent. The son may be struggling to find his place in the family or in society, and the parents play a role in shaping or influencing that identity. Also, themes of responsibility are likely. The parents have a responsibility towards the son's upbringing, and as the son grows, he may have responsibilities towards his aging parents. And of course, themes of love in all its forms - parental love, filial love - are almost certain to be part of the story.
Definitely. The story has roots in actual experiences, giving it an authentic touch. However, some creative liberties might have been taken to make it more engaging for the audience.

Well, sometimes it's hard to tell. It might have elements drawn from real life, but could also be a creation of the author's imagination. Maybe you could look for interviews or behind-the-scenes info to find out for sure.
