Korean names often do get swapped. The footballer Park Ji-Sung was very often referred to as Ji-Sung Park. Same is true of several other Korean footballers. Son Heung-Min is a current example. Often talked about as if Son is his given name, or referred to as Heung-Min Son.

Also, possibly part of that reason Korean names may get switched less is because we aren't even aware of the family/given name order. To use your example, I'd imagine plenty of English speakers think 'Bong' is his given name and 'Joon-ho' his family name.

Whereas I think we have a little more cultural familiarity with japanese names, so we recognise certain names as family and certain ones as given names, and switch them to be the order we recognise.

The vibe is not dissimilar to In Bruges, but I'd say it's much bleaker. For me it's in that category of films that I thought were good, but I'll probably never watch again.

Yeah, it's bleak. It's definitely not a comedy drama. It's a dark drama with some very black comedy in it. It's been very misadvertised.

Also, without wanting to give spoilers, I would say it's very specifically not appropriate for your friend.

The Shining. Love it, but it scares me so much that I've only seen it like 3 times in my life.

Whiplash's finale had be absolutely gripped when I saw it at the cinema.

Unlikely one of you hasn't seen it, but Parasite would be an amazing one for doing this with.

The Secret in Their Eyes (the original Argentinian one, not the remake) would be good for this too.
