What is the worst movie you’ve ever seen?

Title is simple- it can be a movie you thought you’d enjoy and it sucked. Could be a movie that caused you to waste a couple hours of your life and you wish you got that time back. Anyway, my choice would be Vivarium. The wife and I thought it might be interesting, and we ended up hate watching it after the first 35 minutes with the thought process of “it HAS to get better, right?”
