I can see why many people would find Rubicon tv show hard to get into. The trailer for the show and the first episode appeared as though a deep, fast moving intelligence arena or encryption conspiracy was being presented. After the second and third episodes the energy appears gone and you're left wondering what the point is.
However, given the nature of the subject matter the above is probably a good thing. The patient are rewarded by the details of the stories taking shape slowly and connecting. The brilliant performances - and they are brilliant, because every single actor/ess is believable as a real character, probably so much so that the apparent dullness of daily life in the show put a lot of viewers off - quickly subdue the watcher into thinking that many characters are bit players. But given time, each one has more depth and cracks than are at first apparent. I believe this will turn into something very different - where every character is important and has a role to play. In a slow burning show like Rubicon dvd, time is what is needed.
Having said that, I am only one or two episodes into being caught by Rubicon dvd set. And it is still just a show. If the writers behind it cannot climax the tendrils of interests properly, it will fall heavily on its face. I would like to see this run, however, as it has the potential to not simply hit the tension-and-reset button between seasons, but be an engaging and truly thought provoking medium for many situations we find ourselves in.
