If you like supernatural stuff without any explanation whatsoever, you may like this movie. It's along the lines of Cloverfield or Blair Witch Project.

While I do enjoy sci-fi and to some extent fantasy, it needs to be credible too. Bird Box just doesn't make any sense and is way overboard with seemingly impossible, made-up stuff, without explanation or even an attempt to rationalize what's going on.

On the plus side, Sandra Bullock is a great actor and she didn't disappoint in this movie.
