Until the last ( and quite frankly ridiculous episode ). There is quite a lot of shoot outs and gory, terrorist based violence. That is where the initial investment in the main protagonists takes speed. Unfortunately, we get sidetracked on a few occasions with random characters that don't give anything to the plot. Add to that, innumerable flashbacks all covering the same scene - I think I couldn't one of the same repeat scenes at least half a dozen times. Back the ending of the series itself ; the episodes 4 and 5 were gut wrenching and extremely well done ( although the rookie/ hero cops were soon forgotten in the plot ). The last episode smacked seriously of a budget that simply ran out and the direction and script became the principal victim.
