There's a lot of them and from this list --> https://www.endlesspopcorn.com/movies-like-the-pursuit-of-happyness/
The next best is the Shawshank Redemption. My good friend who's an engineer suggested me this. I never heard a lot of movies until someone recommends it to me.
And after watching it, I have to watch it the 2nd time around and I just can't stop. Until now, I've got a copy of it on my phone.
Shawshank Redemption is the best!!!
I am sure that there are other members of the forum that have seen the movie and they have the same expression as us when it's about the movie.
If OP hasn't watched it yet then he has to start with that from the list that I've provided to him.
