An unwhelming ending is the only flaw...

Rating: 8/10 (23 December 2018)

The ending did not do this film justice. It wasn't necessarily disappointing. It simply leaves you with unanswered questions. Although that may have been the point, it would have been nice to get a few answers to LARGE questions that arise throughout the movie.
Developing Sandra Bullocks character as to why she is so extreme with her emotional distance would have helped better understand her. Elaborating on the conflict as to why this large epidemic came to pass. Why the "creatures" effect people the way they do (although I don't see them as creatures, myself). Those are just a couple of the outlying questions that come mind.
However, Bullock's acting was very well done. Actually for the most part, all of the acting was very well done. The story line was strong. Kept you wondering.
Just a few answers to some of those questions would have strengthened this film for me.
If the acting wasn't as strong as is was, for me, I would have given this movie a 6.
