20 Movies Destroyed By Their Plot Holes

2012's Prometheus was widely criticized for how stupid its plot and characters were, so hopefully the sequel would do better? "Hold my whisky," Alien: Covenant replied.

This sequel is even sillier, and everything about it is driven by bad decision-making. These supposedly clever scientists go to investigate a creepy planet with no helmets or proper precautions, one of them leans into a dangerous, hatching egg when the clearly dangerous main antagonist David the Android (Michael Fassbender) tells him to, and none of the infected crew members are ever properly quarantined. 

Alien: Covenant also contains one of the worst plot twists in recent memory. It turns out that David has escaped the planet by disguising himself as Walter, a much nicer android who is identical to David. Surely the crew-mates would've done something to check it wasn't David? They should've been able to guess that something like this could happen. This is a movie where many viewers will be too busy marvelling at all these bad decisions to actually get invested in anything that's going on. 

The movie ends on a bleak note, with David in charge of the whole ship and about to experiment on the thousands of sleeping colonists; a ballsy ending, but one which felt frustratingly unearned. If people like this crew were actually put in charge of important missions in space, humanity would be doomed.
