I stopped watched W a few weeks back actually, at Episode 10, but managed to catch up and finished the last episode today.
I have mixed feelings about the drama. It started out really good but somehow along the way, it was very hard to keep up with the drama. That was one of the reason why I stopped watching it for a while before getting back to it.
However, it doesn’t mean that the story is bad or anything like that. In fact, I do think that the quality of the drama is great from start to finish. The graphics and execution were all amazing.
