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).
Solaris, the new version is decent but it’s a totally different movie and just can’t do the original justice.
Second place for me is girl with the dragon tattoo. The original is just better.
Amazing, came here to basically say the same thing about these two. Thanks kind stranger!
But also: Old Boy. Just don’t touch the American version
