Number 2 is especially accurate! It can also happen with bad pronunciation! If I’m getting into the book, the last thing I want is to be jarred out because of someone saying the word wrong! I’m not talking about fantasy names or terms, those will get a pass from me, but with normal everyday words, that’ll throw me right out of the book and sour the experience! It especially sucks when it’s an absolute favorite book!

Another is when they abridge the book, especially when you know the book well, the abridged version just misses so much context! There’s information that is actually relevant that just gets left out, and I really wish they’d go back and offer an unabridged version for those of us who truly love the book!

Edited to add in the second half of my comment that my ADHD decided to draw a blank on! Sorry!
