Yes, I couldn't agree more. Often times that kills it for me in a drama. I'd also like to mention Angry Mom, Misaeng, and Signal as dramas with stronger female characters.
I've learned to shy away from dramas over twenty episodes. But, as this has my two baes Gong Hyo Jin & Jo Jung Suk, watching it is inevitable. Thank you for such an in-depth guide to all of the characters. I've always had an appreciation for GHJ's figure and fashion sense. For me, directing and editing can turn any good script into a pain, but I hope it doesn't get in the way with this one. I can't wait to start watching!!
