Saw it a few days ago. It's one of three movies I've seen this year that gets the stamp of "excellent," and is probably the #2 film I've seen in cinemas all year.
One thing I disagree with in the review here is the 'war ratio' idea, that it would have been better with 2:1 in favor of action, rather than 2:1 in favor of dialogue. Thing is, the war scenes, while excellent, would lead to burnout IMO. It's one of the film's two major flaws, that the final scene, given the style of cinematography, is effectively glorifying the carnage, while prior to this, the carnage was to demonstrate that, well, "war is hell." I also never got the sense of being preached at, like, ever. Doss gives his belief, and those beliefs are discussed, but the movie never goes down the route of trying to 'convert' the audience.
The only other real flaw is that I feel the film jumps around a bit - Doss gets through his court martial, then we jump to Okinawa. I think the film would have benifitted by showing some of Doss's training as a medic. His interest in medicine is established beforehand, but I think it could have benefitted from the extra material. Oh, and the historical footage at the end was, IMO, out of place. A nice thought, but it feels like a needless tack-on to what is otherwise a strong ending.
So, yeah. Absolutely loved it.
