Bird Box is worth the watch if you're into post-apocolyptic stories. The acting is convincing and they've painted a great cinematic picture. I personally would loved to have seen this as a series rather than a movie, as this would give us more opportunity to learn about the why and how of these creatures, as well as the journey of survival within those 5 years separating the flashbacks, and what happens after the movie ends. It feels.. unfinished. Although the lack of clear answers is somewhat part of its charm, I'm disapointed that the filmmakers hintedat those unaffected (or shall we say, differently affected) being mentally disturbed. I would like to learn why the creatures affected them differently. This however leads into a rabit hole of other questions that the movie left unanswered, so perhaps they purposely left us in suspense. Another option is that they opted for a cheap secondary antagonist without giving it much back story, but I don't know if this was was perhaps explained in the book but the movie left it out. What still makes it a 7 for me, is that Bird Box managed to stick in my head for some time after watching. All in all the level of entertainment I got from wondering about this story was perhaps just as fun as watching the movie itself.
