Well, maybe 'black and white' was the wrong expression.... what I meant was 'Here are the White Hawks, there is an enemy, let's produce come blood'. It was kind of too easy. They had great and deep subjects, but they could have made more out of them. This is what I like about FF. There is not one red thread swimming through each scene... there are a lot of different coloured threads, meeting each other from time to time.
About the blood-effect.... it is always a question of the extend... I guess if they had used less blood, they could have achieved the same effect. After 5 parts my senses were numb. So there was no emotional effect any more. I don't know, if that was intended.
