I always felt that there was an element of stupidity throughout the series. More so out of sheer panic and the fact that these characters, despite their qualifications, are in over their heads.
- Kain approaching the eggs, and Dallas bringing back Kain back to the shit. Disregarding quarantine.
- Gorman disarming the marines and sending them into the hive on their rescue mission. Also, Burk trying to sabotage the mission in order to bring back samples to the company.
- The prisoners generally fucking up and 85 giving in to WY's orders to land on Fury 161.
- Prometheus, which mostly goes without saying.
In this one, I felt like there wasn't too much out of the ordinary. Tennessee's order to lower ship initially bugged me, as he was risking the entire colony, but it ended up working to get a signal through regardless. For me, complaining too much about how stupid the characters are in this series sorta goes against one of the main motivators for the plot of all of them.
