I've got to say, I've conflicted feelings about the second game. I think it was well made, but it left me emotionally drained like nothing I've felt before. The endless cycle of vengeance and violence combined with forcing you to play both sides was taxing, it was bleak as all hell, to the point of not enjoyable as an entertainment medium at the end. Really felt the "an eye for an eye and the whole world goes blind" message.
And I'm not sure you can convene that the passive viewers, so I'd be curious to see the reactions. But then again, it's HBO, and it certainly would be violent, bold, shocking at times and intense, so why the hell not.
