i would say the end of the movie be not believable . i be a bit afraid to have ben affleck a ryan . i have see the the other two movie with harrison ford . i would say he be credible a a young ryan . the part show the work at the cia and ryan try tho show it view be good . the russian be schematically play by the actor . it look like they just go out of their cavern . still the cold war vision . the end start from the explosion be non believable . have the president of the united state start a nuclear war with just the opinion of four person in a plane look unbelievable to me . i press or i press not the button . bah ok i press it . and zou no more earth . vincent ( belgium ) .
