For me, Shutter is one of the best Asian horror movies. I remember watching it when I was younger and the twist gave me a chill. I am not easily scared of horror films, so I personally like this one.
There are many great Asian horror films that I can recommend. Some of my favorites include "The Eye" (2002), "Audition" (1999), "The Ring" (1998), "Shutter" (2004), "The Grudge" (2002), and "Dark Water" (2002).
