It has permanently scarred me. This might indeed be one of the best, most thought-provoking, intense, tear jerker which will give you an insight into the harsh brutalities and realities of life under the Nazi regime. It is more haunting than any horror movie you'll watch because this is real. From the perspective of the innocent Bruno, it will make you feel so many emotions throughout and leave you speechless. I literally could not speak for the next ten minutes after the movie ended. I was just staring at the end credits, crying because what makes it worse is that such things really happened irl. Totally recommend to read the book as well and do not watch this alone. It will move your heart and make you realize so many things. It scarred me. Seriously, just go watch this. There's pain, there's friendship, so many feelings.
one spoiler ahead:
the total last scene where the clothes are kept in the room where they remove it haunts me. because those are the clothes of the people who are now dead. I cried like crazy watching it.
