A lot of people are comparing this movie to "A Quiet Place", the main thing they have in common is the characters can't use one of their senses to survive from a danger (vision in Bird Box as opposed sound in A Quiet Place); the overall plot and danger in the 2 movies starts out similar but the movies take different directions. It doesn't matter if Bird Box is based on a book that was written before A Quiet Place, this is a movie review site not a which script came first originally debate site. A Quiet Place beat Bird Box in terms of film release date so of course people are going to compare it to A Quiet Place. Regardless, when I watched Bird Box I was immediately reminded of M. Night Shyamalan's "The Happening", so I watched it right afterward. The two movies are extremely similar (without the not using vision aspect). Bird Box has better acting in my opinion, but in The Happening the ending is much more realistic and the movie as a whole is a lot more freaky. I disliked the ending in Bird Box, but I enjoyed the movie and I would recommend it, but definitely check out The Happening, I feel it did a better job overall of telling a similar story. Bird Box uses the "character take a risky journey to a supposed safe haven" trope that is used in so many zombie movies (28 days later). The movie is nothing new but it's worth checking out, I'm loving these Netflix original movies raising the bar on quality
