Cue intro to movie...
Text says "Prometheus...crew of 17."
Crew wakes up. You are introducted to 9 of the seventeen. 8 shall remain "nameless" (if only they had red shirts)
As prior explained, guy with the mapping technology forgets he has it nor does he ask the ship that has a 3d model of the entire base for assistance so he gets lost.
He then goes in the room he wouldn't go in earlier. He camps there inexplicabily and then he dies.
Forward to the last 45 minutes of the movie....
Ships pilot: Hey that guy who got lost and we found dead awhile ago. His suit is pinging outside the door.
I know that he died in the tunnels and so far away we have to use transports to get there, but he somehow made it across miles of open, featureless terrain that we have full view of and made it to the ship.
Ships Captain: Well that is odd. How did he get all the way here? Hey do we have any cameras near the front door?
Ships Pilot: No sir, we have cameras on our suit helmets, our suits, in our rooms, and even guys that fly around and 3d map...but no cameras on the front door.
Ships Captain: That is as stupid as having a medical pod only rigged to males on a mixed sex crew ship. Oh well...who is in the main hatch?
Ships Pilot: The nameless guys sir.
Ships Captain: The nameless guys? Okay as long as no plot character is in jeapordy, open the door.
***Giant hatch opens, easily weighing tons and could crush something as it folds up and down, not side to side like a conventional door. Dead body is folded up unmoving at precisely the first place door would not crush him.***
***Nameless guy sees horrificly contorted body and walks up to it.****
Nameless guy 1: Sir, I confirm it is the guy who died in the alien building. No sign of how a dead body ended up miles from where we left it but I think it is safe to turn my back on it.
***Body animates as a gorilla like monster and kills Nameless 1. Monkey man begins killing nameless crew members****
Nameless guy 3: It's killing all us nameless guys....it is killing us all....
Captain: Hey we do have a camera in the main bay. That is handy. Yep those nameless guys are getting killed. Better get some named people down there to contain the situation.
***main guys show up and situation handled***
