This movie was fine overall, you can tell it's based off a book because the only good parts are the broad themes and writing, and because the biggest problems stemmed from the pacing of forcing this book into a 2 hour run time. Everything else from directing to editing to acting is mostly uninspired all together, half the scenes feel more like a sitcom than a thriller. I haven't read the book but it seems better than this bland mess. P.S. it's ripping off of the happening more than a quiet place.
