Last night I saw the movie Morgan. The movie is outwardly presented as a small group of some corporation that is producing a human weapon, but this weapon has gone wrong and must be killed. Initial attempts to kill the new woman fail and she kills most of the group, but for some reason leaves alive a few people, one of whom has been sent there to kill her, and who then does kill her.
Then, it is revealed that the assassin sent to kill the hybrid is actually a hybrid herself. . . and it becomes clear that the other hybrid has failed by not being ruthless enough and by not killing all of her opponents.
