I'd say give it like another 2-3 episodes, if you still don't like it drop it. It's the first kdrama I ever watched (not a fan of romance either) and I really enjoyed it.
Well technically it's true, but I'd word it differently. You probably had different expectations, therefore didn't understand the messages in the drama itself due to it being different to what you expected. Same goes for pretty much everyone hating on it.
I don't often rate dramas a 9 or 10, and this was an easy 9.5/10 for me. Just say your brain couldn't comprehend…
I see almost no one disliking/thinking this is bad outside of the kdrama community. It's just something different that "they" don't enjoy. The top rated shows on this site say it all really.
How is the action?
I'm saying the taste is shit.
