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).
Funny Games shouldn’t really count because it’s the same director with an actual budget to do what he wanted to do in the first place.
I never realised. And I still like the original better.
I didn’t realise that. But I agree.
