The Alien franchise is a beloved horror and sci-fi staple, so naturally Hollywood tries to breathe new life into it every few years. In 2012, Ridley Scott made his return to the universe of Alien with Prometheus-- a not-quite prequel that follows a space crew as they deal with some scary alien threats called Engineers.

Prometheus does raise some questions though. Like why haven’t the crew been briefed on their mission until AFTER they’ve been in cryo-sleep for several years? Why does everybody take off their helmets in an alien cave? How did they get lost in the cave with amazing mapping technology? Why did they suddenly want to touch that horrifying alien snake thing? Why did David spike Charlie’s drink? What was the point of Weyland plot twist? Why was that Engineer chasing Elizabeth at the end?
