Prometheus (Orgin Movie of ALIEN) SPOILER ALERT

Rating: 7/10 (21 September 2012)

CHARACTER DEVELOPMENT
Audience must remember the Prometheus crew was put together by Weylands own private funds. He was intrigued by Shaw/Holloway research then put together a crew. Weyland personally thought everyone was the best in their field. They'd never worked together and hadn't even been told about the reasearch till ship was about to orbit.
Its not Ridleys flaw in character development, it is Weylands: A trillionaire throwing his money around without a clue of how to outfit space exploration or rules to engage possible alien contact or quarentine protocal. Everything fell apart and the characters acted right on!
CLARITY OF CONCEPT
The humans have their own ideas and hidden agendas concerning the aliens, yet while their curiosity and terror drives the movie its only a backdrop to the more interesting storyline.
!!!OUTBREAK of powerful evolutionary stimulant and ORGIN of ALIEN!!!
These aliens produce a powerful evolutionary stimulant, smart enough not to make it on their home planet for all the obvious reasons but not smart about how to store it. Canisters held remains of dead test subjects (beginning of movie alien turned into black goo as stimulant shredded his DNA) Canisters were placed in underground tombs (supposed to be why ancient Earth civilizations follow this example for the dead)
MISTAKE #1 Canisters should have been placed in "clean rooms". Soil contains too much microscopic life, much of which is in larval form and in need of a host to reproduce and complete life cycle -movie shows night crawlers in the ground and they eat soil. The first significant change would have been with the night crawlers into the eel-like things. How it changed from there, movie doesn't show but it destroys the alien crew.
MISTAKE #2 (Holloway drinks from tainted glass) Hollowaywas changing into alien yes, but that powerful evolutionary stimulant did a number on the microscopic organisms in his digestive tract, they mutated and he became infested with them (eye). Mutated sperm got Shaw pregnant (face grabber, hatching out of a human ovum/egg) then ALIEN as we somewhat know it.
GROUND ZERO: Microscopic parasitic organisms. EXPLAINS: Why life cycle must involve retuning to digestive tract. It must have acid for blood to survive that environment. Evolutionary stimulant explains why Alien changes with each encounter. (ALIEN 3 it was more dog-like- ALIEN vs PREDATOR it looked like a Predator)
