This is Hyper Halloween selection, the Nun is the most recent spin off from the conjuring franchise based on the cases of demonologists Ed and Lorriane Warren.
The movie launches at an abbey located in Romania 1952, where a series of paranormal events were being reported, the movie has a touch of ancient holy priestly horror, kind of makes it forced and expected, but the fright scenes are heart stopping, you should add this one to your halloween unholy collection.

Thank you, please do not forget to comment, your opinion is very much welcome and appreciated, thanks
