I'm actually not sure how to describe this movie, but I'll give it my best shot. First of all, Viggo Mortensen is outstanding as Nikolai, a driver and enforcer for the Russian Mafia, and full time baby-sitter to Kirill, the wayward son of Mafia boss Semyon. He's one cold, emotionless dude when he has to be, but has a human side that peeps out ever so often from behind that steely, chiseled mug.
Vincent Cassel (Kirill) and Armin Mueller-Stahl (Semyon) are also extremely convincing, the former as a violent drunk and the latter as the charming and affable, but very cruel father. Naomi Watts doesn't light up the screen and steal the show as she normally does, but it could be the depressing role of Anna, a midwife who delivers a baby for a fourteen year old girl who doesn't make it off the operating table.
Anne Frank may have left a more famous diary, but the diary of the unfortunate young woman is so revealing that some people are prepared to kill to keep the contents from being brought to light.
Fascinating in some aspects, such as the story behind the tattoos, and graphic in quite a few others, including a memorable scene with a totally nude Viggo battling against guys with linoleum knives, I found some parts a bit too long and drawn out, and some too predictable.
Never-the-less, the acting, the casting and the intensity of this drama make it extremely watchable (if you like this movie genre), and although it isn't going to be one of my favorite movies, it certainly is worth mentioning here.
