Ok lets see
Life cycle of the alien, poison, infect someone, infected someone fucks someone, fucked someone gives birth to face hugger, face hugger grows FUCKING X-BOX HUGE for no reason with no source of food, face hugger infects another alien, other alien skips chest buster sequence of growth and gives birth to a full formed xenomorph.
that's just... stupid. Also the black good that turns what I'm guessing were worms into dick snakes? How does that work? So worms get to turn into giant super strong fuck you creatures with acid blood that instantly regrow there own heads. That... doesn't make any sense.
Also why the fuck, when finding a giant alien body on an alien world, does the biologist of the team go "Fuck it I'm out" why the fuck did you think you were there you dumb cunt, you're a fucking biologist in space, that kind of fucking implies dealing with aliens
Also sorry, btu making a movie explicitly to not explain anything makes your movie stupid. It doesn't make it vauge and intersting and intriguing. It just makes it irritating. Old sci-fi greats left mystery sure. But this movie didn't just leave msyeries, it gave enough explination that it didn't feel like leaving mysteries, it felt like they just are only half explaining anything.
