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).
You can always watch it for the meme.
It isn’t quite unhinged enough to be on my personal list of “So bad it’s epic”, but I still think it can be enjoyed ironically. But I mean, at some point one also has to accept their own mortality and ask themselves if they want to spend anymore time on terrible movies or if they prefer to watch good movies for the rest of their lives. I’m in the latter category, which is why I haven’t updated my “So bad it’s epic” list in close to a decade at this point. It’s just to say, that I understand if you choose to skip this one, lol.
