Short answer: Big.
The Hong sisters can be hit or miss with me, but usually I think of them as having a fun premise with charismatic characters. But Big was such an epic disaster. Master’s Sun did a bit to redeem themselves, but Warm and Cozy was a total snoozefest. So instead of going, “oh, yay, a Hong Sisters drama! This will probably be fun, like You’re Beautiful or My Girl or Sassy Girl or My Girlfriend is a Gumiho or Hong Gil Dong!” I now go, “ahhhh, hmmm, the Hong sisters… okay… maybe this will be good, but… not going to have expectations…”
Their early stuff was fun and enjoyable and cracktastic, but I just haven’t felt that from them in their last few projects. And did I mention Big?
