Should Have Read The Reviews Instead Of the Total Rating

Rating: 3/10 (22 November 2012)

When I saw a rating of over 7 I went out and ordered the DVD. I wish I read the individual reviews instead because those who hated the film were so right on target.
Now I will admit that I knew it was a film by the creator of Aliens but did not know it was a prequel till the end when I recognized the monster. Also understood what was first to be a quest to find out how man was actually created which would eventually go haywire, but I expected a lot of plot twists and turns. It started out quite interesting but then slowly slipped into a combination of confusion and boredom by being nothing more than another repackaged survival movie.
But there were also so many unanswered questions which I thought would fall into place as the movie went on - but didn't.
1) Why did the alien at the beginning commit suicide? It was only at the very end that I gathered being the last survivor, he (or she? LOL) did not want to become a carrier and return to his (or her) home planet.
2) What was David really trying to do? It seemed he was there to try and find what he thought could extend the life of the dying old man who referred to him as son. But why not let the daughter see what he was doing? Did the father not trust her? Then why put a drop of alien fluid into one's drink? What was he hoping to discover - the fountain of youth? Did he expect the guy was going to make love, get the girl pregnant and give birth to a new specie? How would that save the life of a dying old man? Or did he simply want to see what happened for the sake of science?
3) Of course, there was no answer as to why those who created us now wanted to destroy us - if they were even our creators after all. However, I think that might come in the sequel but by now, as Rett Butler said to Scarlet O'Hare, I frankly don't give a damn.
Had I known how bad a movie this was, I would have waited to have seen in on cable rather than spent my money on a wasted DVD.
