I've seen the movie and read the book and they're rather different. I thought the book was better because it's more detailed, but the movie has more action and deaths. A lot of the hype around Bird Box was created and driven by Netflix itself. Otherwise, I'm not sure it would be that popular. Sandra Bolluck did an amazing job in the lead role (naturally). Trevante Rhodes and John Malkovich performed well too. It's a decent movie and worth watching if you have a Netflix subscription, but it isn't the best movie ever as memes and hype would have you believe.
