the last house ending explained and why it's a whole vibe

The Rundown

okay so it's about this family who literally run into the guys who killed their daughter on their vacation and plot twist they become the villains. it's wild how fast it turns from 'let's stay in the safe house' to 'we built a torture chamber in the basement'. basically it's a 'house guests' gone horribly wrong. it's a lot but definitely didn't see the end coming.
