This is no old boy

You're absolutely correct with your statement. It is indeed neither of those films. Films that are also not Oldboy or Sympathy for Mr. Vengeance include Star Wars: The Force Awakens, Mad Max: Fury Road, Hobgoblins and many, many more.

If you're referring to quality, that's another matter altogether.

I heard a rumor they were getting married but someone left the papers in Japan.

This is no Oldboy... but this is The Handmaiden.

No this one is called 'The Handmaiden' hope this clears up any confusion for you.

While it aint Old Boy. I still very much enjoyed this movies along with a few friends.

very few movies can ever reach old boy territory since that twist ending was so utterly massive that it can't be done again without someone else guessing it.

True but how many films actually do compare to Oldboy? The Handmaiden is still a really good movie!
