I always thought a found footage style movie from the perspective of the Colonial Marines would be neat. That first encounter scene in Aliens when they are getting picked off one by one while Ripley and Gorman watch hopelessly inside the APC. I imagine their personal cameras video broadcasts were saved somewhere.
This one is looking better and better. I saw Prometheus again. I saw a recap of Prometheus on youtube and made it even better when a watched it again. I really like the direction the franchise has taken. Thank God it veered away from Alien vs Predator territory.
