The mission to save Ryan = the message that war is stupid
No doubt — the actions by the soldiers (like Tom Hanks and Tom Sizemore) were heroic and commendable.
However - we cannot lose sight of one detail: the mission to retrieve Ryan was downright wasteful and idiotic. They might have saved Ryan, but 4 or 5 of them die, including Hanks (who was a captain). Ryan himself didn’t even want to go back when they found him; had Ryan known about the mission, he would’ve told them not to come.
The problem is that the decision to bring Ryan home was made by some big-shot dude in a comfortable office, who read Lincoln’s letter and felt romantic about the situation. The guy was too far from the war to adequately make the decision. The decision should’ve been made by the guys on the ground, who were seeing the blood and guts. And the guys on the ground knew better than to send a team to find Ryan.
Through the sheer idiocy of the mission to Save Private Ryan, the movie effectively conveys the message that war is stupid
