The original series (#1) was outstanding in direction, character development, and action scenes. A great story with many twists and turns. Sequel 2 was a bit boring with acting ensemble not as engaging, but lots of action. Sequel 3 had too many flashback scenes which were interruptive and confusing to follow the thread of the story. All in all, not a bad series to watch the story unfold with intrigue and action.
