It didn't bother me that much, but I watched the Netflix show about a year or so before I read the book so my memories were a little fuzzy. It made some of the early flirting with Luke a bit weird but that was about it really.

I also just finished reading this a few weeks ago (followed by a rewatch of the almost-entirely-unrelated Netflix series of the same name). I really loved experiencing the whole thing through Eleanor's eyes without ever knowing whether the things that were happening had actually happened or not, only knowing that Eleanor had perceived them to happen that way.
