Was the violence to cover for a mediocre movie?

Rating: 5/10 (31 August 2012)

I had heard much about this movie and was pleased to be able to watch it digitally.
I was pleased because it gave me the chance to skip forward through the boredom and the unnecessary violence.
The acting was poor. Each characters was like a cut-out from an old Agatha Christie novel - except instead of false clues to keep you guessing this one adds in rape, torture and Nazis.
Looking back I would say that the movie depended too much on the two main characters - neither of which were played well enough.
I read in other reviews that the book is better than the movie. That wouldn't be hard, but knowing the outcome I won't be reading it now.
I would have given it more points but I truly feel like I simply wasted my time watching this.
