OK, so I only watched the first half of one episode, but it stank. Did not care what happened to any of the characters. And I'm from Texas, and know a lot of oil men, and have run across a few con men in my law practice.
So, I'm unsurprised by the cancellation, but a little surprised by the few news pieces I saw on the show not mentioning how bad it was but instead blaming the audience. Typical critical arrogance.
Newsflash. Better either give the viewers someone they can like -- and boyish good looks but may be ambiguous about being a criminal isn't enough -- or make it really interesting. I.e., Weeds wherein everyone is odious but at least unusual.
