I'm an American and I love old movies. To think back on all the movies and TV shows I've watched it's hard to narrow it down. Also since the movies are old it's possible you're already seen them. But here are some suggestions. I like them because they show people facing challenges and difficulties in life and overcoming them.
I watch Bengali series, so if you understand Bengali you can watch 'Rani Rashmoni' which is related to Indian History and social evils during the British Rule. The story goes back to the time of Rani Rashmoni childhood who build the 'Dakshineswar Temple'. It was the time of Raja Ram Mohan Roy and Rani Rashmoni and her husband supported the 'Sati Movement' and also the movement of child education.
She was a lady who was married into a family who worshipped 'Raghyvir' but proved that God is one, by believing in Kali. She proved that God is one in whichever form you worship him. She visited Kalighat and prayed which did bring results.
She was opposed by the elders of her family but when miracles happened they believed in her thoughts. Her husband too did not believe in God but it was she who through her devotion and faith convinced him. It was also the time of Lord Ram Krishna
She fought against the Britisher's injustice on farmers and the Indian Landlords. You can keep watching for the further story.
