The first couple of episodes were great but the quality of the acting and the writing seemed to go downhill from there. The final episode was a mess as the writers struggled to tie together all the key plot elements and it became a bit ridiculous.
Overall I still felt this was worth watching. It is a fascinating look at extremism and violence. It shines the spotlight on both right-wing racists and left-wing anarchists. Although these two groups are at opposite ends of the political spectrum they are similar in that they believe unquestioningly in their in political ideals and don't hesitate to use violence to achieve them. The irony is that both sides spend most of their time fighting each other and achieving nothing politically.
I think most people could see the hypocrisy and stupidity of these two groups for what they are. Although there does seem to be a risk that some people who already hold extreme views would see the fictional story as confirming their own biases.
