For me, it has to be “Old Boy” which is originally a Korean movie but the US version sucks so much that it remains incomparable. Another contender is “The Ring” again a Japanese movie (the ending differs between both versions, as the original one refers to the protagonist’s father sacrificing himself but the remake states that the cursed tape is being sent to someone else, passing the omen towards another stranger).
The eye
Korean horror. The u.s one is bad like how the old boy remake is bad.
The original was a Pang Brothers film. Like. The audacity to think they could do better.
