I watch Prometheus before Alien because Scott said that it would change the context in which we used to see Alien. It does. As for as the "2012 film before a 1979 film" paradox, I figure that not only did tug crews dress differently than science crews and that tugboats are POS ships compared to science vessels, that during the decades that had passed between the two stories not only had styles changed but that the merger with Yutani may have dragged Weyland down a bit instead of making things better, especially for the working stiffs.
