I wasn't too happy with the storyline in the 3rd season, but overall I enjoyed M more than almost any other sci-fi show in recent years. I include Expanse in this comparison---clearly a better show in many ways, but not much damn fun, to be honest. Dark Matter's writers kept us entertained for three seasons with some frolicking interstellar hijinks. The actors made a good ensemble. Whatever the secret sauce the DM team used to turn a pretty silly concept into a tight, interesting show, I wish they would share it with the Expanse team.
