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 Magnificent Seven is fine.
Seven Samurai, however, blows it out of the water.
Every Kurosawa film blows it’s Western counterpart out of the water
I disagree.
I love both movies, and think that the american version can stand on its own.
