I enjoyed it. As one of the only people in the theater, I was a little annoyed by the dynamic duo of assholes who laughed hysterically and snorted during all the serious parts, but yeah.
It's a solid revenge flick. The critics complaining about mixing up too many different elements seem pretty strange to me, as it's the plot development and some semblance of attachment to characters that makes the violence particularly worthwhile.
There are plot holes...why aren't the crime scenes full of physical evidence, and why isn't kevin bacon's character in jail for the entire movie...but it's pretty tough to avoid 'em and still write this story, so I forgive. Some scenes that try to connect emotionally really fail altogether, but I'm still glad they're there.
It's filmed well, with a distinctive style and coherent flow of action.
16% Fresh, 8% cream of the crop? Very harsh.
