In the British/colonial/exploration genre of film, this is upper shelf.

Rating: 7/10 (12 January 2018)

Currently at the top of my 'I wasn't expecting to like this' list.
I was reluctant to look at this as Hunnam does not have a good track record, for me. But continued praise and 'best movies you've missed' lists made me reconsider
My opinion is raised somewhat after this. My opinion of Pattinson continues to rise.
The little 'fails' are due primarily to the need for drama, such as the over-amped bombastics of the RNG lecture. Yes, there were ridiculous arguments in the Society over intractable preconceptions, and it's very possible that those very words were spoken. But in my nit-picky fashion I feel I can sense when the director has decided to 'juice it up a little'.
