I have to say the tension in the Tony/Carla/factory scenes were somewhat spoiled for me by the amount of time the police took to do anything about it. They arrive at the scene and are told there is a gunman inside with a hostage who is about to set fire to the factory and all they do is stop the crowd getting nearer. SO19 arrive and they took ages to do anything as well, even when smoke started pouring out of the factory...I was just thinking, when are the police going to get a move on!
