Have you watched it? I really liked this movie; but I am somehow intrigued by the ending. I mean it starts with Colter being tranfered in someone else's body without knowing what's happening. His mission now is to find a bomb inside that train. He does a great job and finds it after a multiple times of failing to find the psycopath who put that bomb there. He told Goodwin to switch him off after sending him and she did. The other guy working with Goodwin wanted to use him as a tool to find other possible threats. Furthermore, she switched the soldier off and the movie ends with him kissing Christina and creating a whole new Universe where the whole train survives.
