I liked the discussion these two had, and it prompted me to check this out again. And again, I'm left unimpressed. It's dark certainly, but I wouldn't say it was along the lines of the Disturbo 13 or anything. It's probably the least entertaining of all his movies. There's very few 'fun' moments that you can make fun of. It's unpleasant, but it isn't really disturbing either. I thought it was better than Schindler's List though.
As far as Italo Nazisploitation goes, I still prefer The Beast in Heat.
