For me:
The Ring (2002). I own this, and I have only watched it like twice since its release nearly 20 years ago. The thing that gets me is Naomi Watt’s character (her performance) is so convincing, you either might believe or your just in shock (her I mean). Anyway the jump scares aren’t there like a typical horror flick. Instead its pure camera work, locations, and acting. 8/10. Wish the sequel was as good…
