I love the storyline of the caracters.
Mostly amateurish. Understand that people are still portrated as trainees, but there are life and death situations that could have been executed in a more professional way as it is handled in real life.
The car hanging over the bridge - lots of heavy things could have been put in the boot to stable the car. Why not in the first place get rid of the cars blocking the road - after much hanna hanna parra the brainwave hit someone? Chief should have been taken away from the scene after his breakdown.
