THIS POST CONTAINS SPOILERS
Alright, just got done watching the movie and I didn't see anywhere else to have a talk about these two subjects. While I feel like a lot of people, very split on the movie, there are three things that carry over from prometheus that have me confused and kind of angry: The lack of basic science in the movie, the lack of realistic behavior of the characters that are supoosedly trained in these exact scenarios, and the unfitting religeous overtones.
Science: Why on earth can't those multi-hundred million dollar movies do basic wikipedia searches? Right at the beginning of the movie I saw two very inaccuracies.
1. Wayland was talking about humans being the result of "random molecular chance". This is not how evolution works, we are the product of billions of years of natural selection. All our flaws and perfections comes as the result of previous animals being genetically selected against by their enviorment. Why would someone as smart as Wayland not understand this, and why would he assume that we had to have creators? It's a complete non sequitur.
2. When the ship gets hit by a Neutrino blast, why did it mess up their ship? Why on earth did the writers choose the one particle that almost never interacts with normal matter, so much so that scientists have to build giant lead detectors deep underground just to have a mere chance at detecting them? Why not a gamma blast, or antimatter or literally anything other than the least likely particle to do anything to the ship? Hell I would have rather he said Takeon Pulse and shrugged it off as a nod to scifi fans.
Behavior: Why do none of the characters act rationally? I'm not talking about general panic, I understand people can do stupid stuff while an alien rape monster is attacking them, but even under calm situations they did everything wrong.
1. Why did it take until they discovered wheat that they realized something was weird with the planet? You'd think that the very presence of earth trees would be enough to raise some eyebrows.
2. Like Prometheus, why did everyone assume the air was safe to breathe and harmful microbes wouldn't pose a problem? Why did they think it was okay to go wading around in water with who knows what growing in it? Even on earth we have brain eating amoebas killing a few swimmers every year.
3. Why did that guy assume that spore producing plants would be a good idea to stick their face in? Even on earth I wouldn't do that, but on an alien planet?
4. Why is it when they noticed they had infected crew they're first reaction was to get close to them, not worry about being infected via breath/saliva/mucus/blood and then try to drag them back onto the ship to potentially infect its surfaces?
5. Why did Walter, who supposedly was 100% committed to his crew, never tell any of them about David being insane despite having several chances to do so?
6. Why did the Captain stick his face in the egg when not 5 minutes ago he was willing to shoot David for showing affection for the xenomorphs?
Religion: Why is religion written into this film so badly? Why was Shaw so obsessed with it? Why was the Captain so obsessed with it? Why did the characters keep talking about faith and Creators? I don't mind having a religious character, but it seems so ham-fisted, did Riddely Scott become born again and has to tell everyone? The religious overtones never lead anywhere, the characters keep refering to it and the plot keeps beating you over the head with it but there never seems to be any message or moral. It seems like a very sad and obvious attempt to add artificial depth to the movie.
