To put it succinctly, the movie is vividly full of both gorgeous environmental scenery and the horrific carnage of war.The storyline, on the other hand, is terribly empty coupled with some realism problems (i.e., as if they didn't hire a military advisor). It's like all the effort went into the former, and very little into the latter.

To keep from any spoilers, I will put this generally, even in the film's culmination- which took nearly two hours to build- it felt utterly lackluster.
