Awful, terrible script, incoherent, multi themes going no where

Rating: 1/10 (8 June 2012)

As part of an experiment I once watched a film called Two headed Shark attack (or something like that) but what I learned was even the worse B film can master tension and follow some sort of believable plot. This film failed so bad I cannot believe Ridley Scot did it. 15 minutes into the film the first issue was the dialog and the jumping from theme to theme. It didn't flow, it didn't transition. It didn't sit to explain the universe in which the film was to be born into.
Now unlike most people I did a few course in script writing. And i would love for someone to tell me this script was good. There is no tension, none. I actually stopped caring why the aliens want to destroy Earth Maybe to destroy Hollywood from making anymore films like this.
Please tell me you invested in those empty unrealistic characters, apart from The robot and Theron I really cant remember one person. have no idea who did the casting. Compare the African American to the original African American in Alien. Compare Weavers role in 1-4 (and I complained about 4). You see where I am going. The film has in too many unresolved unexplained, unrealistic themes. Two many aliens, mismatch of boring parts from far too many places, too many motives. Then the last 14 minutes they reveal some silly motive which makes no sense whats so ever. And the film rushes to deal with the threat, what do they do? Get a 1/2 interested captain to grow some deep spirituality (not previous developed in the character) and...Well See independence Day collision for the 20th time in Sci-Fi history.
Someone noted that there was a scientist who didn't behave or speak like a scientist there were too many stretches. Boring love affairs, alien implantation, late term abortions, crazy Giant Alien, Father- Daughter inheritance theme, the black oil from X-Files, Captain and Boss booty call, Catholic religious themes, redundant details, redundant scenes and focus (which did not develop) random.com theme, Waste my time theme Help me * "The alien air is breathable so I will take of my helmet" * I will get drunk 2nd day of the mission, alcohol available on a mission Tell NASA * They took off their helmets, where did they put them * A glitch, but the captain wants to get laid * They camp/sleep in a nest full of suspicious egg bombs * For no reason Robot poisons guy, wants alien baby, but also wants woman hero to be safe *Post operation she is fitter than Serena Wiliams.
Visuals are good, 3D not needed (took off my glasses 1/2 way)
Now lets deal with the dead dialog. Who seriously wrote those lines? It pops out of the script and makes no sense 1/2 the time. "I am not here to be your friend I am here for the money"-- how does this fit the theme. How is that continued (as in the case of Alien 1 with the money issue for shares (which is properly introduced to add motive to the film?). Strange bunch of disjointed people who look mostly like heroin addicts. Too much things not quiet right to have to have faith with. Aliens create humans who want them to come to there WMD site to knock of their heads? Sorry maybe my Mother wasted her money on my education but I don't follow. non sequitur.
It is possible the greatest disappointment in recent memory. What a waste of an opportunity.
