Two things didn't work out for me in this movie..
1. Really ? You couldn't give her a better name than ''Goodwin'' ?
2. When Sean asked Derek Frost why he planted the bomb, he said: ''Because the world is hell.''
This is perhaps one of the dumbest reasons to explode a train I've ever heard. Couldn't you (the writers) give him a better line than ''the world is hell'' ?
