Evokes powerful, often uncomfortable questions about morality, justice, vengeance, and the dangerously sketchy line that separates the three. A suspenseful thrill-ride from beginning to end, but be warned; this is not a movie for the faint of heart. I went into this movie more than a bit squeamishly due to the subject matter, but found my efforts well rewarded as I became enraptured in an unconventional plot spinning in unexpected and yet believable directions.
