There are other reviews, this is just a comment. Movie is decent, ignore the haters.
Does have some issues (didn't know Nazi Germany was still fighting in fall of '45), plot meanderings, weak points and not exactly a master thespian cast but has some good horror moments, decent banter and semi-plausible character interactions.
The interesting thing about this movie is its orientation toward not showing the ultraviolence in all its dripping glory. The most visually graphic scene is when one character has his finger broken.
Personally, I am utterly sick of watching 80 minutes of CGI anatomy trying to take the place of a story. This movie has the sense to use the cutaway (ha ha) approach to violence and I respect it.
I would watch this movie 100 times over any of that Saw (post Saw 1, which I thought was pretty good) / Hostel torture voyeurism or Rob Zombie crap remake any day.
