Why does this have a 7 rating overall?

Rating: 3/10 (19 April 2019)

It's a shame to categorize this movie as "horror." There's nothing scary about it. There's killing involved and a weak plot, but it's not horror. The movie attempted to create a plot twist but not enough information was given.
There's also a "post-apocalypse" feel to it.
If you're looking for a horror movie, this movie is not for you.
If you're okay with plot holes and having questions unanswered throughout the movie, this movie is for you.
