Ridley Scott decided to make a "point of view" story, told by the main characters. Now, when you use this kind of technique you have two options. You can do the same sequence with little variations, but short length (e.g. "Hero), or you can portray totally different scenes, so in the end all the pieces fall into place (e.g. "Knives Out").
If you don't follow one of the above you end up with a movie like this one. Two and a half hours of the same sequence over and over again, each of which add small (and often non-essential) information. This could have worked, as an hour and a half movie.
