What? Why? Where? How?

Rating: 3/10 (25 June 2012)

I went to see this near the end of its run in the UK, and was forced to ante-up GBP10 for the privilege of watching it in 3D.
I'd read the mixed reviews, but (as a big fan of Deep Rising, which is universally hated by even moderately-minded film fans) decided to give it a chance anyway. I have to say it was a complete waste of a tenner. Apart from a few nice touches showing it as the prequel to the Alien quadrilogy, the only good thing was the SFX - except that they could have filmed the whole thing in some remote part of Iceland and saved themselves a few million dollars in CGI.
Apart from that, my summary of the film is a series of questions about the absolute stupidity of it all, as described in excruciating and accurate detail by previous reviewers.
The up-in-the-air ending does indeed leave one wondering if there is going to be a Prometheus II (or should that be Alien 0?) which explains some of the rubbish proposed in this epic. Leaving aside some of the more specific inanities (like why did they not use an old actor to play old man Weyland, instead of a young guy in poor make-up?) in favour of the bigger picture....
Why did the aliens leave cryptic messages giving the location of a bioweapons development planet, whose apparent 2000-year-old delayed mission was to destroy life on Earth (having created it for no obvious reason in the first place)? Surely that's the last place they would want us to visit, in case we blew up the ship they intended to use to kill us. Oh. Ooops.
Why did mankind spend a trillion dollars sending a bunch of squabbling retards and misfits to investigate this strange new world instead of a team of clever people?
What screen writer fresh from his First Grade biology exam designed the life cycle of the aliens? Where did that Cobra thing come from? Why did the black cloudy stuff turn humans into indestructible monsters (rather than just poisoning them dead), who could then impregnate other humans leading to an embryo that could gestate in 11 hours, before turning into a giant squid? Uh? What? Why?
What was all that garbage about bringing the head back to life, and it then exploding? That woman was an archaeologist, was she not? When did an archaeologist ever manage to bring a two-millennia old alien head back to life - and then fail to turn off the juice so it goes 'bang'?
And what was the story of the 'mechanics'? How come all of them were dead bar one, who had spent 2000 years in stasis. If the ship still worked, why wait 2000 years to wake up and complete the mission?
Why did Weyland hide out on his own ship? What was the point of the blonde ice-maiden being his daughter?
Why have a sophisticated medical scanner/diagnostic/operative device on a ship with male and female crew programmed to only work for men?
Since when did stapling someone's skin together after an operation allow them to perform superhuman feats within minutes afterwards? I had my appendix out, and with all the resources the NHS could throw at it, I could hardly walk for a week afterwards.
And the silliest bit of the film is where the alien spaceship crashes, and then starts rolling like a giant wheel towards the two women, who then run - in the same direction the craft is rolling. I mean, come on, Mr Screenwriter - this is supposed to be serious sci-fi, not College Co-eds meet the Wolfman!
Words fail me. As some have pointed out, maybe there will be a Director's Cut which explains some of the greater idiocies - for instance that the crew are cretins because of budgetary limitations at NASA.
