Some movies are entertaining, some are unforgettable, and then there are those that leave you staring at the screen wondering why you put yourself through them. Certain films are so intense that watching them once feels like enough for a lifetime. They might be brutally emotional, deeply disturbing, relentlessly tense, or simply too difficult to sit through again. People on Reddit have shared the movies that affected them that way, and their answers cover plenty of different genres and experiences. Some choices are famous for being difficult watches, while others are surprisingly personal, proving that a movie does not need to be universally terrifying to stick with someone.

Grave of the Fireflies (1988)
