They get on board the dropship to go to the planet. No one was left in the ship. Is this wise? Thankfully there was a transmitter on site and Bishop could do those things he did. What if the transmitter was damaged? What if Bishop was damaged? What if there was a fire or system failure up there in orbit with no one to respond to it?share
There were 60~ families. No response from any of them. What if there was some sort of rage virus epidemic? What if everyone turned into vicious monsters? (like Dead Space). That could be 60~ violent hostiles, all with home-field advantage and surprise on their side. They send one squad only? They clearly did not send enough people.
Gorman being in command, despite his lack of experience in actual missions. Remember how he was panicking, resulting in a lot of marines getting killed and capture, and he still has the arrogance to ignore Ripley.
Gorman orders Apone to collect magazines, yet did not mention the important reason why there shouldn't have been firing. Vasquez's blatant disregard for her NCO's orders regardless if they had been told why. Vasquez was still holding and swinging her smart gun as if it had ammo, no one found this suspicious? Why did she not shoulder it?
Everyone was ignoring Ripley a lot in the beginning, the person with the most info and exp regarding the enemies they were facing.
Dropship takes off after leaving them, and lands somewhere in the same area. That place was definitely not secure. Co-pilot also left the ramp down while ... what was he doing out there anyway?
You set off to explore an alien world with unforgiving terrain and you bring along a vehicle that hugs the ground like a Lamborghini sportscar? You won't even clear most modern Earth road humps with that.
