Any personal reviews of the movie “Heart of a Lion” with Dev Patel?

It’s based on an extraordinary true story: a little boy begging at a train station in India gets caught on a train & lost thousands of miles away in another city. He eventually ends up in an orphanage & is adopted by Australians but remains deeply haunted by memories of his mom & older brother & wants to find them. As a young man, using satellite imagery on the internet, he somehow finds his way back to them.

A TV interview with the real fellow, who now lives in Tasmania, showed footage of his return home to his mom & learning that his older brother who got separated from him at the train station was killed that very day by a train.

Is that an extraordinary story, or what? Is the movie worthy of the story or is it rendered maudlin?
