Boring. From the first episode the whole story is unrealistic and sometimes even ridiculous. This is not how prison, court, police and lawyers work. Everything is so fake. Stupid guy doing stupid things, one after another, until the end and public servants jumping over their heads to save his pathetic life and bring justice. Didn't care what would happen to him at any moment. Why making movie about someone like that, not to mention whole series?
The only thing that worked well was ever present uncertainty, which lasted until the end but from the other side sometimes it led to even more bizarre scenes and some threads were left unfinished.
