I'll join the positive reviews of those who loved the series, even though I hate the fact that we're stuck with a cliffhanger that will never be resolved because BBC America gave the people actually writing and making the series no warning whatsoever about its cancellation. The third season had already been planned out with regard to its plot, and that's what the ending of season 2 led up to.That being said, I loved season 2. I felt it had all the strengths of season 1 when it came to intelligence, gritty realism and great characters and actors, but with a more coherent plot and with less of a character who really got on my nerves (the kid Annie). I don't want to give too much away about the plot, so I will just say that while it goes on telling the private stories of the characters, it now also delves more deeply into the dealings of the powerful businessmen of the city and just how ruthless they are.Reading some of the negative reviews, my impression is that some of those reviewers didn't realise just how complex and detailled (and great) the plot was. In hindsight, lots of small details that didn't seem that significant or weren't explained at first suddenly made (sometimes shocking) sense. To me, it really paid of to watch it on Blu ray within a few days so that everything eas fresh in my mind. I'll watch both seasons again right away since I'll certainly understand even more details and connections.This was a really intelligent series that made demands on its viewers. I hate that it was cut off mid-story, but would nevertheless recommend it to people who love a good plot and interesting, realistic characters, but who can handle the fact that there are no 100% good (or even bad) characters and that there's a lot of violence and some sex. It might appeal to you if you liked Deadwood, but series like Justified or even Battlestar Galactica also come to mind for intelligence and gritty storytelling. I just wish the series had been given more seasons - what a waste of talent to cut it off after only two.
