This is clever stuff - exposing corruption and shady dealings in the Congo with a script that deftly provides plausible reasons for why characters are drawn into such murky depths. It continuously wrong foots you and never lets go of a pace with often surprising and shocking turns that deal with the big issues of life - trust, love, betrayal, ethical dilemmas, politics - without ever getting ponderous. Highly recommend - and good luck trying to stop watching once you've started!
