Honestly, this series started off really promising. I mean sure, I wasn't a fan of how the whole 'extreme-makeover' situation was handled, but with a cast like that, I was HYPED-- And then, the Fire Nation attacked.
Characters and entire sub-plots were built up, only to be dropped at a moment's notice; nothing made sense, and the plot soon started to feel repetitive and dull-- I mean, is it just me, or does 'murder' kinda lose its edge after the 8th resurrection? At times, I truly did feel like I was watching Dragonball Z again...

Let's take, for example, the character of Hee-jin. Remember how, at one point, she was in pretty much every other scene? That is, until her mother's body got thrown into the sea as part of Oh Tae-jin's 'Pro-gamer move' (which felt both anticlimactic and pointless). After that, we didn't see her again until the very last episode- and that too, only in the drama equivalent of 'you won't believe what they're doing now' clickbait! Seriously, there were so many plot-holes and unanswered questions: how did Cha Min come back? What happened to the real Ji-Uk in the end? WHY WAS SEO IN-GUK A DOG???

I guess what I'm saying is, if you take your drama with milk, sugar or actual resolution, maybe you should skip this one.
