I never liked how Night was forced onto everyone in high school. Reading it and being told it was truth felt extremely dishonest a left a bad taste in my mouth. In hindsight maybe it was a good thing for me, but plenty of people in my grade accepted it as truth.
When I was forced to read it, I thought it was a work of fiction. Dude was 15 when he experienced all this which then published in 1956, 10 years later. By default, being that young at 15 and being traumatized in a concentration camp is going to screw with your memory. The accounts are just so over the top and any 15 year old is going to be an unreliable narrator simply because they are an adolescent. If thats how he felt in the camps, fine, but don't call it a non-fiction memoir. Im sure parts are true but the book as a whole reads like a romanticized blog post series.
Listening to grown men, American soldiers' accounts who liberated the camps would have been more effective at convincing me of the holocaust horrors at that age than Night ever did.
