Getting over the utter implausibility of the plot is the only way to be able to watch and enjoy this. And I have to say I enjoyed it over period of 24 hours during which I watched the lot. What helps is that Alberto Ammann playing Hugo Roca is such a hunk.
Put aside the identities of the attackers and the utter impossibility of a prison being cut off and besieged with no one in the world noticing and one can lose oneself in the profound deliciousness of wondering what the writers will have us accept next.
Much has been said about the inconclusive ending. I can't believe there won't be another season - there are far too many loose ends to clear up. This could have been resolved with the addition of a couple of episodes but as the producers stopped at just six this strongly indicates to me that there will be more to come next year. I can think of ways that the new season could be stretched to six more episodes.
When it comes I'll be watching.
