Prometheus is a puzzle *spoilers*

Rating: 9/10 (22 June 2012)

If you watch Prometheus you are likely to leave the cinema with more questions than answers. The plot is full of holes. Characters act in bizarre ways and very little makes any actual sense. Although visually it is stunning this lack of any real answers many viewers initially disappointed. Myself included.
However Ridley Scott is a genius and he has either cobbled something together or Prometheus is indeed a puzzle where all the pieces fit together in a sequel (or two).
Having read many theories I think there may be a simple explanation.
SPOILERS BELOW
1) The cave map is not an invitation. In 2001: A space odyssey the aliens leave a marker on the moon and the "prize" of a stargate for humans when they reach a certain level of technological advancement.
In Prometheus the cave paintings are a trap. If you have reached such a level of technology then you represent a threat to the engineers. Follow the map to LV-223 and you will be destroyed.
2) Engineers (I believe the name is a clue) can both "create" and "destroy" life. At the beginning of the film the engineer is making a religious sacrifice to "create" life on earth. "Black goo" is used to destroy a planet.
3) Weyland wants to harness this massive power to create to expand his lifespan - hence funding the expedition.
4) "Black Goo" is a means of destruction and the captain is correct that "black goo" is a weapon. Whatever it infects it infects with Alien-esque properties. It grows fast, acid for blood, wants to destroy etc The Alien we see in the 1979 film is the realisation of "black goo" DNA.
REASONS THIS THEORY WORKS: 1) This is why David infects the drink. He works for Weyland and is testing whether the goo will preserve life. As we know however this is not life creating but black goo(In the mini-trailer David 8 said he could perform tasks (and experiments) which humans may find morally objectionable.)
2) In my opinion this "black goo" DNA explains all the monsters in the movie including the end scene.
3) The "threat" idea also explains why the Engineer "freaks out" at the end. He is a warrior and a guard. If anyone arrives on the planet they are a "threat" and must be destroyed.
REVIEW CLOSING COMMENTS So after some thought and based on the above I am moving to the conclusion that Prometheus is brilliant. I think there is a debate as to whether this level of puzzle making is good cinema but I think it works and completes the story. Even holes like "why would a geologist get lost" kind of make sense when you think that the objective of the mission was to save Weyland. Sacrifice some of the crew. Send them the wrong way for example if it may create a result. (for example David 8 had no concern for Shaw - only for the creature)-"Crew Expendable".
So there you have my theory. I look forward to the call from Ridley Scott and confirmation of my prize. (I am 6ft 6 so working as an Engineer extra would be fine). As a film I would say that Prometheus is visually stunning, well acted and intriguing. It really does reboot the franchise and I am sure the sequels will be even better. Loved it. 9/10 (will move to 10/10 if theory is correct).
