There a couple things that qualify, but The New World with Colin Farrel is always a go-to answer for questions like this.
This movie sucks through and through and the ending doesn’t help things. It’s boring beyond belief, and even though it had a regular length it feels like you’ve been watching this thing for four hours. Nothing really happens, and it moves unbelievably slow. Until like fifteen minutes before the end. Then all of a sudden decades fly by; Colin Farrel goes back to England then goes back to the New World then gets a kid which grows up discovers a cure for cancer and builds a spaceship to go to Mars and then he dies which we really need to feel very sad about. Okay obviously he doesn’t go to Mars but you get the idea.
I actually watched this in the cinema, and apparently my opinion of it was much like that of the rest of the audience. When it was over, someone behind me blurted out “Wat een kutfilm”. I’ll let you guess what that means. I should’ve gone to Ice Age instead in the next room.
