I would definitely say I loved the movie. Conjuring has always been more than just a horror movie, and to see how beautifully concluded it was, I really enjoyed it. As far as the horror part, there were a lot of good jump scares, and I thoroughly enjoyed it till the very end.
I don't know what exactly, a lot of people saying that they didn't like it or enjoyed it, but as far as the judgment falls on me, I would say it was 7 out of 10 on a scale of horror level. The execution of the storyline was definitely 10 out of 10. I would recommend more people to give this movie a try.
