Best horror movie

I love to watch foreign horror movies, especially the Korean and Japanese ones.
The original "The Ring",
"The Wailing",
"Ju-On",
"A Tale of Two Sisters",
"Train to Busan",
"I Saw the Devil" <--(My Favorite Movie of all time)

There are so many that I've watched, but don't feel like putting down. Definitely check out some of those Horror Movies though!
