I really liked this film and I don't agree with the "white saviour" criticism it got. I felt at different times both of the main characters saved the other. I did feel the homosexuality was glossed over too quickly, why put it in the film at all if you are not going to explore that side of his character too? Apart from those minor quibbles, I thought it was great and well deserved its Oscar.
"Inspired by a true story". I'm not sure how factually accurate it is, and it seems to gloss over some key aspects of the characters. But there's a very specific story here - a fun and heartwarming film about connection between people. And on that level it works.
It looks great, seems to capture the time and place very well and has a foot-tapping soundtrack.
