Ambiguity and things being unexplained is fine with, I get that. If this movie wanted that maybe there shouldn't have half explained things then. My problem with the movie is that things were either illogical or not internally consistent with the universe the movie setup. I'm sure some of you would say these are nitpicks (I would agree) but when there is so many of them it really takes me out of the movie and wrecks the atmosphere. Especially when so many of these things could have been fixed so easily.
It's a trillion dollar mission and the only scientist they can find are ones "in it for the money" because those are the best scientists right?
5 dots leads them to conclude alien life created them?
Almost all of them agree to be frozen for two years with no idea what the mission actually is.
The biologist refers to evolution as Darwinism (nit pick for sure, but they could have made a phone call to any scientist about this one).
They figure out the atmosphere is oxygen so they remove their masks with complete disregard for pathogens (better looking to not have masks on, fine)
Masks are internally lit for some reason and have condensation (looks cool, fine)
The biologist sees alien life for the first time and even though it's been dead for 2000 years he is scared of it and the room, leaves.
The biologist and geologist who as far as the movie goer can tell are in constant communication with the ship that has a 3D map, manage to get lost.
The rest of the crew, without thinking, leave them behind.
The two of them go back to the room that they were too scared to go into in the first place to sleep! Buh?!
The biologist, who apparently is a scientist, sees alien life (second time) tries to coax it toward him like a puppy. How very scientific of him. He is scared of dead alien life but not alive ones? Wah?
They stimulate the head and it explodes for some reason.
The DNA match is exact even though they are 9' tall.
The guy scientist finds alien life and is a brooding a-hole about it for no clear reason.
The alien snake thing turns the geologist into a zombie with super human strength for some reason.
The guy scientist has a snake thing in his eye and tells no one (guess he doesn't have to, you would think a scientist would)
Charlize's character doesn't want the infection guy on board so she opens the biggest door on the ship.
The infected girl is in quarantine, knocks out some dudes who never show up again.
The medical pod in Charlize's personal quarters which is tailored for her and is a separate ship, is only for men (I guess it's for the old guy then).
The old guy is not dead for some reason. Certainly no good reason, because they don't provide one.
It makes no sense why a younger guy plays an old man. The makeup is so awful it took me out of the movie. He is barely in the movie, they should have just used an old man.
They no longer care about her being infected and/or why she has a giant scar.
She can run around and lower heavy bags of stuff with seemingly little pain despite having abdominal surgery moments before. (she grunts a few times, oh right)
The old man is Charlize's father which the movie makes out to be this big reveal. But everyone saw it coming, doesn't care, and it didn't matter.
The working class ships captain who is only "in it for money" and doesn't care about the science in the mission, has a change of heart and decides to sacrifice himself to take down the ship.
While that was boarder line in terms of believability, the reason the other two go down with the ship was because of a side bet! A side bet! Insanity.
They run away from a falling doughnut like idiots (
duh)
The main actress talks about her Christianity a lot, but the only thing Christian about her is that she wears a cross. They could have done more with this.
These are things that could have easily been fixed. You'll notice I didn't point out things like the opening sequence, most of the characters motivations, why the aliens seeded Earth and then decided to retract the offer of life, why the alien ripped David's head off and started rampaging, etc. I'm fine with leaving those over arcing things vague and/or unanswered. I don't need my hand held, but don't make me leave my brain at the door either. This movie didn't need to have so much illogical things in it. I think the movie needed to either be longer or had some characters be cut. There was too many and except for David none of them were fleshed out. The environment, technology and effects were great, but the rest was lacking. I am still holding out hope for a longer directors cut.
