First episode really didn't do much for me. Cheng doesn't have much charisma and his ideas aren't very deep, and are often a bit cliché. Pass.
Two episodes in and not very impressed. It's well done, but just feels like every other cop drama out there. The immigration stuff is certainly topical, but is handled in the bluntest, least nuanced way possible. A show were almost every character clearly represents an idea more than a human being.
