I bought the Bird Box book some years back and absolutely loved it. It has a unique plot and is the kind that will stick with you through the years especially if you are able to visualize whatever you read.

This movie is based on that book. It is NOT a movie that was inspired by another. However, the movie does have some differences that, overall, make it less enjoyable if you have read the book. But maybe that's just me.

On its own, the movie is fine, though I feel the plot would've been better left as just the book. I've been wanting to see Bird Box on the big screen but quite frankly it could've been better.
