Although the intentions are very noble (showing the world how Navajo Indians helped in the war ... through their native language as code), the movie is not that good ...

You would love to give it more kudos (at least I would), but even Nicolas Cages performance just doesn't really grip you ... you are left emotionless/cold. You don't really care for them or what will happen to them. And that is a death certificate (excuse the pun) for this movie. The fact that he had to cut down the movie, so that it would be cinema-friendlier, didn't help either ... so if you're going to watch this movie anyway, go watch the Director's Cut, because you will get more back story and emphasis on the characters.
