Dumb decisions in the alien series that everyone ignored.

You know how everyone is complaining about prometheous and covenant for having stupid people who make stupid decisions? well people are going way to hard on them and they never noticed any of these dumb decisions from alien  and aliens. the 2 crticly aclaimed ones.

Alien:

dallas breaks quarantine to let kane in with a face hugger on him. 

the crew goes to the planet even before they have decoded the message that they got from it.

dallas and ash wear no protective headgear while doing an autopsy of an alien corpse.

when they go into the room were kane is and the face hugger is gone they leave the doar open so if it were still alive, it could escape onto the ship.

when kane just suddenly feels better after the facehugging they dont do any phisical examination.

they all risk there lifes time and time again to to catch jonsey the cat.

Aliens:

they dont just send robots to investigate lv 426.

know one listens to ripley. the only one who has ever seen and delt with them.

they all fire there guns inside the nucular reactor.

they forget to check that the celings are blocked when they barricade the room.

burk trys to escape from the xenomorphs by running into the hallways even thought there are xenomorphs in them and they are sealed off.

ripley spends 5 minutes torching all of the alien eggs agrovating the queen when thw whole place was going to get nuked anyway.

ripley thinks that her arm can withstand the entire vacuum of space when she drops the queen out into space.

these were the dumb desitions that I saw. do you guys have anymore and do you agree with me that people are judging the prequels to harshly? let me know in the comments
