Really nice, really short
Excellent work in what you have done... but... I really think it is silly to let the intro text be almost as long as the movie itself. Granted, this probably took you a while to make, but World War 2 should've been way WAY WAY more described than 30 seconds of intro text, 20 seconds of action, and 20 seconds of concluding text.
I'm afraid I cannot give this a high simply because its too short. If you had let your focus on a certain part of the war, or just a battle or something like it, it would've gotten higher. But this is like baking a cake, and only having the dough at the bottom. (Which DOES taste sweet, but just isn't the same as the whole cake)
