I don't think that movie would ever be motivational. It feels like a male-centered film. I figure these family sentiments exist everywhere, but in our countries, most females can't speak much. I don't know what it is. people say rude things. I'm often rude myself, but the ability to say nothing back or feel that it doesn't matter makes it harder. As with your mother, I feel the same about mine. She seems so selfless; I don't think I could ever match that. I often notice she doesn't indulge herself much; I have to encourage her to do things for herself.
We should fill our cup first, only then we can care for others. Above all don't do it for people pleasing because you can never make them pleased with yourself, only one mistake and then BOOM.
