A technical marvel. The film is shot gorgeously. The soundtrack is incredible. The colors are wonderful. Yeah, visually and sonically, this is perhaps one of the greatest cinematic achievements.
Unfortunately, problems arise in the other main design choices - respect. The actors are all natives, the film is shot on location, and the story is simply told as it is known in order to be respectful of the people bring talked about. That's all great in theory but, in practice, the acting is subpar and the story is really nothing incredible. Unlike Scorsese's other two faith works, this one doesn't have any groundbreaking themes or ideas. It's just the story told cleanly.
I wanted to love this. But no matter how great the film is visually and sonically, the material is really nothing incredible and it's made worse by less than stellar acting.
