If a movie can be spoiled by revealing a plot twist, it’s not a good movie. There are a lot of great movies with great plot twist, but even if you know the twist, the movie is not ruined at all and is endlessly rewatchable.

This is why I hate mysteries. Like Murder on the Orient Express. The most interesting part is the ending and the rest of it is a forgettable man with a moustache talking to other forgettable people for two hours about forgettable stuff. The worst episode of Law and Order is better than any given mystery story.
