Given that it never achieved the kind of ratings gotten by Mad Men and Breaking Bad, I guess it makes sense that AMC, after getting extraordinary ratings for The Walking Dead, would choose to cancel its suspenseful conspiracy series, Rubicon.
AMC’s third series [and first cancelation], Rubicon was smart, finely textured, richly detailed and mesmerizing. And now it’s gone. A statement from the network says, "Rubicon gave us an opportunity to tell a rich and compelling story and we’re very proud of the series. This was not an easy decision, but we are grateful to have had the opportunity to work with such a phenomenally talented and dedicated team."
