An excellent addition to this genre. I recently watched a quiet place which I like a bit more than this one.

Bird box gets you wondering, what the heck is happening and it never really answers that question. Which I felt like needed a bit more flushing out. The length of the movie mixed with the shallowness of the plot left me a little wanting.

The movie is rated R so that helped raise the tension especially since you start to wonder, will they kill all the main characters? Sandra Bullock puts in a solid performance.

All in all I would say a very entertaining movie that I wouldn't bother watching again but definitely worth watching once.
