First 2 episodes are very entertaining, making it easy to ignore the few unbelievable things like introducing the impulsive coke head brother as well as the witness of another criminal organisation to the top secret weed operations everyone seems to know about.
However in the 3rd episode the series becomes a joke. Duke has to steal a car because this massive organisation doesn't have anyone else to do it? Their trusted weed delivery guy drives around stoned, attracting attention, with a critical load of weed without a helper / any GPS tracking and so loses his key? How have they been in business for so many years? It fully stops making sense and couldn't continue to watch. Like the director outsourced the remaining episodes to an intern.
