This is a prequel. - major spoilers in the offset!

Rating: Null/10 (4 June 2012)

Anyone who has seen this and still says it isn't a prequel is basically either an idiot or just trying to be stupid and shallow minded.
It explains about the space jockeys ( how is that not a prequel ) It expalins how the ship crashed that the crew in alien find ( how is that not a prequel ) It shows the beginning of the eggs featured in the alien films ( how is this not a prequel ) It clearly shoes xenomorph type characters carved into the walls and ceiling.. It shows the beginning of a bloody xenomorph exploding out of someone at the end of the film, or did the people that say they weren't in the film walk out before the end? There was more but cant be bothered to go into any more detail. This IS a prequel but also stands out in its own film for people that haven't seen the other ones.
My only real problems with the film were the fact the she could run around and absail after having a c section. Believe me, you cant. Also was promised a terrifying experience and it wasn't. You will find the worm things no worse than something you would see in pirates of the Caribbean. That being said, loved the film, not perfect but will certainly be up for a sequel.
Not a bloody prequel, sheesh!
