Superb movie from an excellent novel

Rating: 10/10 (5 January 2019)

I'm taken aback, having watched this brilliant movie, to come onto this site to find I'm in a significant minority of people who actually rated this film highly. I'd read the book, which I suspect now is an advantage because I wasn't expecting things such as explanation of the "monsters", let alone visuals of them, or resolution of certain plot lines. The genius of the novel is that the protagonists are thrown into an apocalyptic situation that escalates too quickly for anyone to "take charge", "save the day", or "come up with explanations". Things are what they are and the few people left alive cope as well as they can or they die. The movie brilliantly captures this sense of unknowing. The whole point of the story is that you don't/can't see the monsters. I spent the entire novel and movie wondering if I'd have the self-control not to look... The temptation must have been overwhelming.
Perhaps some of the negative reviews came from viewers who thought this was a horror film--it's not. It's an intense psychological thriller with little gore and fewer jump scares.
Perhaps this is one film where I'd suggest reading the book first rather than the other way around?
Highly recommended.
