I saw it this weekend too. Normal cinema not imax. Really enjoyed it. I read the book a year ago therefore I didn’t remember every detail of the story, didn’t bother me if minor stuff changed as I might not be remembering it right anyway. I think it was true to the main story and and vibe, very nicely done. The actress who played Eva was perfect casting too. The dead pan line deliveries were brilliant! Agree with your 4.5/5. Feel good movie, good antidote to the current state of the world.
