Neither fish nor fowl

Rating: 2/10 (1 June 2012)

I went to this film with high hopes and have created this IMDb account so that I can write a review about it. The first half ( subjectively ) of the film was great: deep and thoughtful. The acting was generally great and where it wasn't, I think the fault lies with the script and the direction rather than with the actors. The CGI was also very good, it wasn't lush and vivid as the CGI was in the film "Avatar" but it almost seemed real, and was appropriate to the tone of the film. To begin with, the 'homages' were subtle and didn't make me think (too much)of the films that they referenced. An example would be the similarity of the 'cockpit' of the "Prometheus" resembling that of the "Nostromo". SPOILERS The film began to (really) lose it's way when the two village idiots encountered the 'snakes', engaging in behaviour so benighted that one would not expect to see in a parody of a horror movie.
I'm finding it hard to continue talking about this film.
SPOILER I will skip a lot of inane events and move on to the 'auto-abortion'. In the film "Alien", which was great and which I love, but is not without flaws: one glaring plot-hole is how the Alien grows from being perhaps 1 foot in height to about 7'.
SPOILER When Shaw removes the creature from her body it is somewhat bigger than a watermelon, when it is encountered later on in the film it has somehow grown to the size of a grizzly bear - what did it feed on?
This film is neither as good as "Alien Resurrection" (pregnant Queen Alien; fecal baby Alien; poorly judged tone; miscasting) nor as good as Alien Versus Predator Requiem, which at least has the dignity to degrade by stages: possibly good film; possibly okay film; creature feature; monster mash etc.
If "Prometheus" had set out it's stand as a schlocky monster movie or a comedy horror I could have enjoyed it on that level...
If there's a sequel I hope Ridley Scott gets replaced by James Cameron.
I also do not have high hopes for how the new "Blade Runner" will turn out.
