Because Bird Box involves removing one of our 5 senses, it is easier to review by comparing it to A Quiet Place, which has the same general concept. A Quiet Place removes sound while Bird Box removes sight, but both films involve a monster that is off screen for the majority of the movie and both films attempt to highlight the difficulty of raising children in their situation. There are other similarities as well, but I can't give more details on those without spoilers.

As A Quiet Place knockoff, it doesn't live up to the standards set by the original. It seems devoid of the suspense required for any monster movie that chooses not to show or delays showing the monster, and that is the primary reason why Bird Box fails to pack a punch. However, Bullock does very well, and the movie concept is still interesting, which will probably make this movie worth watching even though you may not want to rewatch it.
