content: Season 1 was incredible. After that, the series went steadily downhill. I don't know whether they lost the original writers or they just got burned out. Season 4 is totally lacking in imagination. It has a small collection of plot elements constantly reshuffled with slight variations. Pretty soon you realize that anytime there is a scene where Character 1 gets the drop on Character 2, Character 3 will come up from behind and turn the tables by getting the drop on Character 1. Every one of the good guys will have a family member taken hostage by the bad guys. Any time a character appears to have been killed in one episode, there is a pretty good chance the next episode will reveal that they narrowly escaped. The predictability kills the suspense. And the director continues his annoying habit of trying to show tension by having the actors suddenly start gasping like they just ran a marathon. Disappointing.
