Not one actor falls flat in their performance. Their actions seem completely believable in this grim and dark showing of World War II. And it is grim. And it is dark. This movie is stripped of its romanticism, but not its heroism. These men endured much and sacrificed much, and that is what makes its conclusion all the more enthralling.
Of all its parts, only its structure falters. All scenes seem strung together haphazardly, and if not for the character arcs of Brad Pitt and Logan Lerman, one would have no idea why one scene maters to another. It's not until moments before the movie's conclusion that one has any idea what the movie has been progressing to.
