The exhibition also suffered heavily from its need to cram in ALL of Korean popular culture.

That sounds like way too wide of a scope, imho.

Or on queerness in k-dramas, from sporadic appearances by queer secondary characters (e.g. Reply 1997's Joon-hee aka best boi), to the cross-dressing shenanigans of Coffee Prince, Sungkyunkwan Scandal and Painter in the Wind, to the extreme slash potential (+ subtext) of Goblin, to the current crop of BL webdramas.

I would love to go to that exhibition. *adds titles to to-watch list*

(given the scope of the exhibit, it's disapointing the giftshop offerings were so generic and sparse)
