I'm looking for nice, sad films that you enjoy watching when you are alone. By alone I don't mean alone as a person but lonely.
Netflix (possibly also Amazon Prime Video)
FSK from 0 to 16
The green mile has to be seen if you don't know it
I don't know but like to watch it
I can definitely recommend "three steps to you" or "like a single day"
The Green and Schindler's List are one of the saddest films I've seen and I've seen a huge amount
Your Name (Netflix)
A silent voice - the movie (YouTube)
Three steps to you (amazon prime)
The Book Thief
Life is Beautiful
Anne Frank's diary
(Unfortunately I don't know exactly where you can watch the last 3 films: /)
So I would suggest you:
Skins (it's a series but it's sad), if anything happens i love you, Holding the man,
I don't know if these can be found on Netflix:
5 feet apart, all the bright places
