Absolutely awesome
23 October 2003 | by VoodooVinceSee all my reviews

A seriously refreshing police thriller that cranks up the tension to the max. There's no overblown gunplay or buddy cop crap here, this baby is tight as a drum and will have your nails down to the quick. Superb performances, a tight script and tense direction make this a winner in every department. Pick it up if you can, it's fantastic.

9/10
