The lack of answers doesn't bother me, there is enough to interpret about. Why are people ragging about the movie?
Because it's a dumb movie.
"What is this, martian piss?!"
"I just got an abortion and there's a foreign body in the ship but I'm not actually going to mention it."
"I'm black goo. If you fall into a puddle of me, I make you crazy. If you drink me, I decompose you and put worms in your eyelids. If you drink me and have sex with someone, I impregnate them with a squid."
"I'm a xenomorph. The engineers have seemingly seen me before as there is a giant mural of me in the urn room, but in order to create me you seemingly need to...impregnate a human being with a squid and have the squid impregnate an engineer...???"
"I love rocks. I really love rocks! Clearly you DON'T love rocks!"
"Okay, you have a 3D map of the area, you didn't go that far inside the area, and you left before everybody else but the two of you are totally gonna get lost. It's not like your captain will help you either, who also has a 3D map."
That fucking scene where that dude yells like a wolf or coyote or whatever. I don't even know, it was terribly dumb.
Alien and Aliens were good movies for many reasons, one of which being that even though the characters did dumb stuff (especially in the first movie whenever they SPLIT UP HURR DURR), they were pretty competent overall. They were scared and had to improvise and came up with different plans. Nobody in those two movies would try and pet a giant hissing alien cobra that's clearly hostile. The closest thing is Kane looking inside the egg, but an egg is pretty neutral as far as potential hostility is concerned.
