Good symbolism, great imagery, not as solid/believable as Alien(s)

Rating: 8/10 (9 June 2012)

Just saw the movie, then read a review focusing on the 2000 years ago - part. We killed Jesus. And actually, I felt that the most intense moment in the film was Elizabeth Shaw laying on the ground mumbling something remorseful, just before the beheaded David talked to her through her com. The anguish of knowing that your own ambition and risk/hopeful going off on your own (sin? knowledge..?) have damned you to a tortured, wasteful end. Very, very Christian guilt nightmare there. It's like - hey lady you want to doubt God and find Engineers? here you go, sorry you didn't just want to be a good sheep. God was right, now you're super damned and it's all your fault...
Glad that wasn't the real ending. What bothers me about the movie? As in Alien and many other sci-fi movies, creatures are able to grow to tremendous sizes with absolutely no food and in almost no time. The original Alien kind of leaned that way, but maybe it found some food somewhere and was just a fast grower. The octocrotch monster grew from 1-2 pound fetus to a 400-500+ pound giant squid in a few hours while locked in a plastic room, after being gassed. Maybe it eats plastic.
Similarly, as an Engineering Student I've had it drilled into me that it just takes time for liquids to disperse and cells to grow, and the envelope of genetic engineering magic has crossed the line in this film. Much like the scene in FF5 where they drag the giant safe through the city, OMG that was the funniest thing I've ever seen in a film. But back to Prometheus. I don't want it to be funny and ridiculous, I really care about this Universe, and now this cool universe has had weird impossible things forced onto it.
As far as plot points and the way I like to read into it, here goes: (SUPER SPOILERS) Sure after proving that we are incapable of selflessness, maybe the Engineers saw that and developed this black murky bio-weapon stuff that got into the boyfriend's drink. I can buy that. Then because they are so similar to us (genetically), oops somebody (mr. decapitated) got infected and then the bad bio-weapon snakes dispatched everybody except one survivor - almost required in these Alien movies, it seems. But why didn't he proceed directly to Earth? Who knows. We see Mr. Weiland wake him up, get slapped with his own Android's head, which was pretty nice, and then after its ship gets crashed, - for some reason it doesn't get another ship, instead it goes after Elizabeth. Hmmm. I think it should know better after all its buddies got stacked up dead due to free roaming monsters, but whatever. Now after getting your abdominal muscles sliced clear open, I'm almost completely sure you basically can't walk for a few weeks. Hmmm... Magic super-healing Elizabeth, whose womb was infected, but not anything else. Hmmm. But anyway I'm still in love with the series, and It's funny to think that the Alien came from human sperm infected with just a little bit of wormy badness, and that that baby was actually an overgrown boneless face hugger. I really wanted another hour of movie where Elizabeth gets to the other alien home world and the new xenomorph baddie impregnates another space jockey going off world in a spaceship. Also this movie used Geiger's art - was almost all just a pretext to use other artistic ideas of his. The big head on top of the pyramid was actually made for Dune, and the Alien mural was totally just like the baphomet painting. Anyway I'm going to see it a lot more times, but sure wish it could have been more plausible and complete.
