I saw this in a film festival just yesterday. It was not really the sort of film I would go to normally (I'm not really into religious themes in film). I already knew a little of Father Damien's story, and I had a fair idea of how the story would end but I was glad I saw it just the same. I wouldn't say I "enjoyed" it because the subject matter was in many ways depressing but in a way it was an inspiring story. It showed what one man can do to improve the lives of 1000-odd suffering people that the rest of the world has all but forgotten. Damien had a will of iron and he needed it to counter the resistance of the government and his superiors in getting the help he needed.

If this sort of theme appeals to you I'm sure you will appreciate the film, if you definitely don't like religious themes then it's probably better that you don't see it.
