They are both about a single parent who seeks revenge on their daughter's rapists. I find broken better than don't cry mommy. But they are both good movies.
Another revenge movie but this time about a father who will go to any length to avenge his daughter. While I Saw The Devil is rage induced and has your adrenaline pumping throughout, Broken is rage induced but more heart wrenching. Grab a box of tissues and a cup of tea rather than popcorn for this one.
