Realistic or not, the director/producer/whomever is responsible for this movie wallows in long, drawn out scenes. If it's blood, it's bloooood. If it's rain, it's raaaaaaaaaaain. None of that moves the plot along. It only serves to drag out the film. They could easily cut an hour, maybe more, and still tell the story with respect and honor to those who were involved in the actual mission. The movie The Longest Day was far and away a better use of time, even at the length it is.
