Season 1 is unbelievably gripping.

Season 2 is a drag - relies too much on profanity, a linear story line and wanders in the wrong direction of what you thought the ending would be after Season 1. It's not terrible, but it is too diplomatic not wanting to piss off the political masters. Some of the characters who could have been great at the season 1 were left just with abuses in season 2.
