I was very excited about this one because even though a lot of people didn't like Big Dragon, I kind of loved it.
The acting from mosbank is good as always. I can't say anything about the others, too soon.
I think it's too obvious what P'sun's brother's position in the company is. After the first episode, the story looks flat, but the opening scene with the dragon (or snake or other mystical creature) gives me hope. Let's see where the series goes from here. I'll update my review when I've finished the series.
