Things I found annoying: Some of the dubbing is cringy.
-CGI is obvious and repetitious.
-by far the most annoying thing is how slow some of the episodes are but still contain enough events
that I have to go back and watch bits that I skipped...grrr!

Things I found not annoying: Everything else.

I'm annoyed that I didn't wait for the entire production to be added to Viki, now I have to wait to watch the last four episodes...said me, never... regarding a C-drama, yet here we are. I can't give a higher rating for a show than, 'I can't wait for more episodes' or 'I'll watch this again, on purpose' and this series gets both.

You don't have to think a lot while watching but it's still intelligent enough that it will suit a wide range of demographics.

Time well wasted, give it a go.
