The intensity of the horrorness itself is depends on the culture where you are living. For example, for us, asians, hooro movies like Ju-On, Pengabdi Setan, Body#19 are more scary than Dark Water (western adaptation of Ju-On), the Conjuring, etc. Thriller movies like I Know What You Did Last Summer seems scary for americans, but for us Asians, it is more like comedy. Why? Because we are already used to fight brutally, and murderous villains like in Scream and IKWYDLS would only a joke for us. But, Hannibal Lecter is quite thrilling.
