Review of Stalingrad

Despite so many bad reviews I decided to watch the movie. And after I was finished I really couldn't understand why are people hating on it so much. This is not an American movie where soldiers go gun blazing, destroying everything in sight and winning the war/battle. It's a great movie that shows the struggle of Russian people during the war. I even liked the ending. It was sad. But real. Wars are sad. This movie has such a strong message some people can't understand.
