Not just a psycho cop thriller.
The movie also brings up issues regarding race, crime, security, class and masculinity in the modern world. It doesn't fully commit to those themes, but it's not preachy either.
Fully lives up to its R rating with the bloody violence and sex/nudity.
Fun to see Kurt Russell play a suburban beta yuppie who "man's up" at the end. A more interesting take on a similar character he played in "Breakdown."
