I'm a relatively new fan of Horror films but have watched a lot of the classics & all of the Conjuring Universe films (five so far, including this).
I had high hopes for The Nun but it definitely turned out to be one one of the weakest films (right there with Annabelle). It's got no plot, the story is pointless & non existent. The leads act well enough but not enough to save the film. And worst of all, it's save for two half decent jump scares, it's not even scary. An overall weak film that's best avoided.
