.....it might have made a good movie a great movie.

Rating: 7/10 (16 July 2012)

Like many others, I too was awaiting this title, but had less illusions as to outcome. One of the basic plot flaws of the Original Alien movie, was a science android over-ruling the ranking officer and allowing a 'contaminated' crew member back on the ship. The reason such protocols exist is to avoid any conflicting actions in such a crises situation. Any such space ship would have a complete self contained Quarantine that would prevent any contagion -no matter how big or small- from ever entering the ship-vent into space?.
So even though I love the movie Alien, it's just what I expect from Riddle Scott.
This movie had similar suspensions of the very same type of ship protocols, leading to a rapid disintegration and spoiling of the plot. I was disappointed there were in-sufficient aliens in the show like many other movie goers. But I feel an opportunity was lost to explore the possible connection to the new emerging notion of "Ancient Aliens". I wished that had been explored more, it might have made a good movie a great movie.
The TV show/series like 'Life After People' has demonstrated that evidence of a human culture would disappear very quickly after that culture died off. If there was nothing to keep its legacy going, it would just be reclaimed by nature within hundreds of years , while all massive structural evidence would be gone in a matter of thousands of years. Even Neolithic human structures should disappear within tens of thousands of years. Given that archaeological digs cover at most a tiny fraction of a percent of the worlds land surface, we just can't say previous civilizations couldn't have existed. 'Absence of evidence is not evidence of absence'.
So when this idea was hinted at in Prometheus, I was intrigued, only to be disappointed it was only dealt with superficially. Given that the "Prometheus" Ancients were discovered - planning to send the 'Zenomorph' aliens back to earth to wipe out the human race 2000 years ago, one has to wonder why then? What was so special about AD 80-94 time period- that they were planning global human genocide?
Maybe these ancient genetic engineers had finally accepted that with the Roman Empire ...after the Greek Empire and Egyptian before that.... humans had demonstrated their rule always leads to decedent , slavery based civilizations that are too unstable to last or too rebellious/dangerous to utilize for the Engineers own ends.
Here's an interesting article that explores some of this. http://io9.com/5919306/another-theory-about-the-meaning-of-prometheus
