Things We Learned From Watching Barbarian
1. When walking along scary, dark tunnels, be sure to always point your flashlight at the walls of said tunnels and not directly in front of you.
2. Also when down in scary, dark tunnels, and something or someone is down there and bites you, be sure to run in the direction of where said something/someone bit you and not towards the way you came in. Even if someone is trying to tell you/show you the correct way out.
3. If you're an actor/celebrity, be sure to buy a house smack in the middle of a completely empty, bombed out neighborhood in order to turn it into an Airbnb to make some extra income.
4. If you're a homeless person living in a completely empty, bombed out neighborhood, make sure you don't do anything about the one other guy that lives there whom you somehow know to be a sex maniac that kidnaps dozens of women to hold prisoner and breed with.
