This film is actually good and educational. Not a typical Zombie film at all.
I don't understand the negative review. I actually really like this film and I disagree that it has no positive messages. First it provided a jumping point for me to talk about how there are agencies that try to coordinate health efforts across the world. You can talk about how vaccines work, why they are looking for "patient zero" etc. I have to admit I have had some experience in epidemiology, but none of those concepts require more than a cursory internet search. The disease and military dialouge may bore some younger kids. There are plot points they may miss. But mine still enjoyed it and I explained it when it got a little more complicated.
The main character also sacrifices his own desires (to stay and protect his family) for the greater good. This was not completely without pressure, but he does the right thing, and is brave and persistent. There are also brave and smart women in the film. While their screen time isnt long and they are not leads, it is good to see the role models.
It does require some suspension of belief. The main character survives multiple zombie attacks and then a plane crash. If fact only the two characters we are invested in survive the crash (rolled eyes).
The book is also good though nothing like the film. The plots are completely different. They both tell the human story of an epidemic and neither the movie or book emphasizes the gore/blood, gross out material that this genre is known for.
I liked it. I said 13, however my kids are 12 and they were ok with it. I was worried about my daughter's reaction, but she was curious about the vaccines (which play a large role) and the medical take on the "zombies". My son liked the bombs and guns. Neither said they were very scared.
I guess I just have a very different take on the film than the CS reviewer. I think we will have a lot of positive (tho more educational than moral) conversations about the film.
