The film fell down and simply couldn't recover

Rating: 7/10 (16 September 2012)

This review assumes that Alien (the original) has been watched, and it doesn't give away any specifics about Prometheus.
I really had to push myself to give this a '7' but it just about makes that rating.
It was about half way through the movie and things were still quite exciting, but then the plot started to fall apart. This was perhaps due to the sheer weight of the subject matter (God, Aliens, Mankind, future, past, etc). It just seemed like Scott had real difficulty in reconciling all of the issues that he wanted to in making a prequel.
It was like the cart had been put before the horse, because so many people know how great and simple the story gets after all of this has happened, why do we need to watch all of these convoluted issues?
The Aliens are always so majestic, but none of the Aliens, or the Engineer for that matter, was anything near to that.
Near the start of the film one of the characters is quoting from Lawrence of Arabia (about not "minding" pain), and it is a wonderful quote; but the actual dialogue in this film was several leagues below this standard.
Scott is still one of my favourite directors, and is clearly one of the masters of film, but this one just got away from him.
