The gore was unnecessary
It was too much, I guess Tarantino put it in so that we the viewers didn't like the Basterds too much and had to be reminded what they were doing, but it was too much and Tarantino is above torture porn.
I'm not for censorship and some of it was well done, but seeing the scalping and the nazi forhead marking was crude filmmaking (in a bad way), and unneccessary.
This film works best when it is left to the actors, and it is a triumph when it is.
