It's a wonderful show and I highly recommend it.
Too bad they're trying to invent an unnecessary second season instead of filming the second book, Tai-Pan. It's about Western trading companies in Hong Kong at the beginning of China's so-called century of humiliation that followed the first opium war.
How can someone look at all these different styles, let alone the ones that literally look like they're drawn by a six-year-old, and think, "Yeah, that's fine"?
