I dont understand why this movie was so well recieved. They did not do a good job explaining the complex plot, resulting in an anticlimactic ending. The editing and camera work were bothersome, and both the acting and plot where dry despite the good cast. Some scenes were so lame I almost thought they were supposed to be funny. Content wise, I thought it could be PG-13. There is one very bizzare, unrealistic battle scene (later revealed as fake) with no blood. One scene has brainwashed man drown two close friends. Two killed by gunshot, very little blood on bodies. Two horrifying murders where a man is programed to strangle his friend (VERY disturbing, vomiting blood/bleeding from eyes) while his friends look on and do nothing. No sex, drugs, or drinking. A few s---s and one f--- (not that bad).
