Movie is okay?
1. Successor (movie) - The father might be over the top pretending to be dirt poor, but the mindset was right; the heir should be a kind, diligent, smart, compassionate, and healthy person, not the prodigal son who's lazy and spoiled like the older brother.
2. Dhevaprom: Dujupsorn - Jutathep family in Dhevaprom series era were all kind and compassionate. So did Kedsara (the older gen Dhevaprom) and her husband. Even Madam Orn (the great-grandmother of Jutathep family) had changed for the better (but she's trying matchmaking Jutathep-Dhevaprom again in Poncheewan).
3. Destined - ML's family was the richest merchant, even richer than the nation. The parents spoiled the only son but the son is not a bad person, just like martial arts more than studying but in the end trying his hard to study.
