Well, it's not really incredulous that series like this don't make it to top 10 most watched list but 365 or a Dark Desire instantly do.
First off, you need to appreciate more than just nudity and kung fu. Second, you need to see the sarcasm and humour thats lie beneath what some people may say mindless laughter or slapstick jokes.
Okay, its being compared to the Office, but that's unfair to be honest. It may be a work place drama, but it is much more.
Dunno what critics call it but I for one thoroughly enjoyed watching both sesions. 2nd is better to be honest. There's much more focus on character building, and humour sometimes reminded me of Catch 22. Yep, its something like that for me.
I would definitely recommend it.
