I read and enjoyed the book, but the movie improved on some story beats and trimmed some sciencey stuff that wouldn’t have translated well to the screen. Pretty great adaptation.

If you’re considering watching it, do try to avoid the trailers for it. I understand that you have to market the story, but introducing things in ads that should have been delightful surprises kinda stinks.

Does the movie keep the suprise? I’ve read the book, just hoping it pops out of nowhere in the same way.

There are a couple of good surprises, one early-ish and one pretty late. (Trying to avoid spoilers here.)

The early-ish surprise (a character reveal) was a genuine jump-scare for me and I knew exactly what was about to happen. So pretty good.

The later surprise (a revelation about why someone is in their situation) is actually subtly foreshadowed better in the movie than it was in the book. A really great improvement.
