Gratuitous Thrill Ride... And that's about it

Rating: 6/10 (31 December 2018)

Thrilling scariness and horrific violence achieved, however, without any rhyme or reason.
Obviously the filmmakers were intent on including as little exposition as possible. I believe there is none in this film.
At least in 'The Happening', a film very similar to this one, we were given some explanation as to the origin of the plague, neurotoxins or whatever it was.
Everything about the production was first class in my view; the acting, photography, sound, etc. It's just the writing that left something to be desired.
Maybe everything will be explained in a sequel? That's probably not something we should hope for.
