A few things I always wondered about sci-fi movies:
- How come almost no sci-fi soldier ever carried food, water or even bag for extra items?
- In Dune, the entire house Atreides left Caladan to run Arrakis. After they got wiped out and the remaining people clearly never were coming back, whatever happened to the people who lived on Caladan? Who ran the planet after that?
- In Alien/Aliens, the Nostromo was ordered to land on that rock to (maybe) find an alien. The company put Ash on the crew for that reason. So, the ship goes poof and nobody apparently has a clue what happened until Ripley turns up almost 60 years later. The company seriously never thought maybe something was found and decided to divert another ship there once the Nostromo didn't show up?
