WWII from the enemy's point of view, you'll be an eye witness to the fall of their leader and the collapse of the German army at the hands of the Allied forces.
It has a general feel about it, you can feel the tension and atmosphere in the room as they discuss the battle plans. The end is getting closer for the German army and you can feel it, you can feel the fear in their hearts and despite already knowing the climax you keep wondering if there's a possibility the plans will succeed.
The acting is incredible, Hitler is shown in a fair light, he's not played up as being a heartless monster nor is he shown to be a lunatic. He has depth and thanks to a great performance comes alive on screen. The supporting cast also do an amazing job, not a single bad performance in the bunch.
Overall: One of the best WWII movies ever made, facts brought to life and many elements some didn't know of are finally revealed. Brilliant movie from start to finish.
