I watched the Nun yesterday. I am a fan of the Conjuring series (I think the Conjuring films, plus Annabelle: Creation, are not classic but are quite good, kind of for horror what Fast & The Furious are for action).
This Nun, however, is pretty terrible. It’s one of those films that doesn’t realize that if you try to be scary for the entire running time, then it isn’t actually scary at all. You have to show a normal world at least 50% of the time for the scary stuff to hit home. If you have two people wandering a creepy empty monetary at night for the whole film, with a jump scare every 3-5 minutes, it just becomes boring.
