Held off from watching Bird Box because of so many very negative reviews, should have ignored them. A well made movie with very good acting from a great cast, the direction was fine and the movie moved along at a good pace. The movie is based on a novel by Josh Malerman, but his inspiration was definitely John Wyndham's The Day of the Triffids. A lot of issues in the movie are left unanswered, but I think that's good, it leaves you to use your own imagination. A good film to watch.
