As an audience we feel lonely and fragile just like the main character. The movie begins as a horror but slowly turns more action orientated. Early action scenes are very good and unfortunately the get abit repetitive and aren't as good later on. I love all the question this film poses. Set in the back drop of WW1 it does't seem to have connection intill you peice it together. As there aren't many characters in the film you get to know them intimately. Character development is handled well. The CGI looks natural and effects are gratifying. This movie had me hooked and as a result I have ordered the novel it was based upon.
