What constitutes a "horror" movie?

Rating: 3/10 (9 August 2018)

I saw this movie because it had a good score on this site, but neither me nor my three friends enjoyed it. Most of the time we were wondering what this movie was about.
The story is very weak, it's barely scary at all and the acting was bland or even wooden. One of us wanted to leave mid-ways and the thought crossed my mind too.
