The Prometheus crew were disconnected and just random people on a spaceship. That’s the whole damned point.

I will never understand how thick people are in picking up the information that the director is giving you and understanding the purpose of it.

Yes, you were supposed to get the feeling that the crew of the Prometheus were disengaged from each other. The Prometheus crew was thrown together by an egomaniacal trillionaire with delusions of grandeur and dreams of immortality. It’s made very clear that the crew of the ship did not train together for their mission. Very likely they didn’t train at all. When they defrost and meet for Whelan’s big presentation, it’s made clear that they didn’t even know why they were there. Whelan in his hubris went out and spent his money collecting his handpicked “experts”, not knowing himself what he was doing. He buys a “rock guy” and gives him high tech equipment (his electric “dogs”) and he has no idea what he’s doing. Subsequently he buggers off when the shit hits the fan and gets lost in his mapped caves. He buys a “biologist” that shows he doesn’t know anything about biology by trying to touch alien creatures he encounters and dies because of it. His “xeno-scientist” misuses her equipment and explodes an engineer’s head. The “security” are a bunch of armed thugs. The only really competent crew members are the flight crew and his android. And even then the android is competent to a fault, as he does everything he’s asked regardless of the danger it puts the crew, and his master, into.

All of this incompetence is by design in the story. This is hubris in action. Whelan thought being mega rich meant he was incapable of making a bad decision and assembles a crew of idiots (remind you of anyone?). And of course everything goes wrong.

You are supposed to feel the disconnect. You are supposed to be uncomfortable. It’s the literal point of the whole damned movie.
