Yes, she grabbed her stomach every 5 minutes, but you just dont run around after a surgery like this. I get that this is a movie and a sci-fy after all, but what I meant was actually the scenes RIGHT after the surgery. She just gets up from that pod, and runs around like nothing had happened.
When she gets out of the pod she sets it to close and sanitize everything in it, killing the trilobite (as we're obviously supposed to believe). Not sure if she hunched over in pain at that point or not, but yes, you're absolutely right..she did run the entire 5-6 feet out of the room without showing much pain. Then for the rest of the movie she makes it perfectly clear that she's suffering and giving every last bit of strength she has to move on and survive. You need to watch more movies because this is something that is ALWAYS ignored.
Realistically, after a surgery like that she most likely wouldn't be capable of moving. Doy. But the story has to go on and Ridley made it very believable. You can see and feel her pain as she struggles to survive.
There are countless numbers of movies/TV shows where someone gets severely injured, or shot, and doesn't slow down at all or just barely shows any emotion to the damage they've endured.
Tony Stark was thrown out of a solid glass window by a god, without his suit, falls a hundred feet or so and is perfectly fine in The Avengers.
Batman falls a few hundred feet off a building and lands on a car in TDK. No damage. Never hear any complaints about that.
Hell, even Dillon being able to instantly reach over and grab the machine gun on his back and shoot at the Predator after just having his entire right arm blown off was a bit of a stretch.
At least Prometheus showed that the surgery actually meant something. We saw it have a painful affect on her.
...and, as CelticP said, she had taken 3-4 shots of year 2093 space-meds.
And indeed they were going to meet their creator, but that doesnt mean the squid-thing is any lesser priority at that point. You dont know anything about it! As far as you know it could grow to be massive and take over/destroy the ship. How do you get home then? And do not tell me "with the alien ship." Safety first.
What bothered me about it was that noone cared and before David mentioned Shaw's survival instinct I was under the impression noone even knew what had just happened.
I do agree that they should have mentioned it, but I never found it to be that big of a deal because....
1. Weyland could die at any second. He literally only had a few days left if that. Top priority is getting him to the engineer.
2. The trilobite looked dead. Shaw most likely thought she killed it, as we were supposed to believe by it's complete lack of movement after the sanitizing/decontamination spray stuff.
3. Some of Weyland's own personal mercenary guard guys stayed on the ship while him and the others went to wake the engineer.
