Watched some clips, it's fascinating how they managed to make killing Nazi's boring and lifeless, even the caricatures of the Nazi's are boring and rote so there's nothing to really draw you in except the over-exagerrated violence and Whedonesque quips.
It's incredibly sterile. Even the sailors in white suits had 0 blood on them when they got shot, and the one who got his throat slit had a paper cut worth of blood if that!
