first of all and we know that bruce willis be a good actor but if you take the majority of his movie you will see that the character have these moment where they be the same . his character in this movie be far beyond every single one so far . and count . the story begin in the ( not so far ) future where a man be send to the past to find the source of a virus that have sweep most of humanity from the face of the earth . the story seem to go towards sf but i think it closer to a drama because of the slow rhythm of the story . about that . movie tend to be faster and slow at some point and develop more towards the end than the beginning but a you see this movie you will be aware of this constant rhythm of story and reveal fact that do not speed up nor slow down . it the one and the same speed that flow gently and pretty good . but that doesn not mean that the end wont pull your nerve and cause it pretty good . as far a the direction go and it be prefect . movie a such be easily destroy by bad direct but this one have become far well . so and if you be get ready to see a sci fi movie or some action and you will miss it . b there should be more movie like this .
