I just saw the movie this weekend, at 4DX 2D, and I can tell you truthfully I had tons of fun. We went with some friends, after ignoring all the negative and bad reviews over the web. We even heard some of our friends who had already seen the movie, bashing it with negatives, but we decided to go anyway.
I am not a sucker for horror movies, let's just sort that one out, but I loved the previous two Conjuring movies, and had also seen Annabelle. I didn't like Annabelle as much as I did like The Nun. It was something new, a new touch to the story, and although it wasn't directed by James Wan, it was still good!
Yes, it has a lot of jump scares, sometimes predictable, sometimes not, but it's still fun. The rush you feel when the chair you're sitting in starts jerking chaotically and the characters in front of you scream in fear, that's what I was looking for. After all you go to a movie to have fun, not to judge and analyze every bit of it. What would it become of a movie, if everything would be perfect and carefully thought through. I enjoyed the story, even if it felt a bit rushed in the beginning. The eerie feeling the movie gives you, represents a big plus as well. You feel isolated and alone throughout the whole experience, and it makes you feel better when other characters join the action, and the band gets back together. I mean, a priest, a nun who hasn't pledged herself to becoming a full nun and a farmer, well. How bad could this trio be? Let me tell you, they fit perfectly. Although the Nun herself, or let's say Valak, didn't have much screen time, except toward the end, you still felt her/his presence throughout the movie.
Overall a fun and enjoyable ride. A few cliché moments, but still good toward the end. Great effects and a total blast seen at 4DX 2D.
So, if you enjoy horror movies, and you're not one of those fellas who goes to the movie with a pencil and a notebook in his hand, in order to analyze and criticize everything he sees, you're good to go. You'll have fun.
