Great actors, camera, soundtrack, but that's all.
If we remove all "jumpscare" scenes (honestly,I hate jumpscare scenes in all movies and in Smile they looked like a jumpscare from games) it would a movie about woman who went crazy.
Curse thing is okay, but it would be way better if there were less jumpscare and more "horror tension" scenes. Just like in japanese horrors.
I wanted to put a 3 star at first, but let's agree that this was a first great horror movie after co-vid.
