In each character we see truly different people, in each episode we deal with new & interesting topics. We've watched discussions on politics & religion, human rights, corporate rights, right to speak, right to die, we've seen it all.
Each episode we grow to love or hate the characters that are presented before us, the actores are truly brilliant and pull of their character wonderfully well.
The only bad thing I can say about this series is that is has been cancelled. Perhaps some time in the future we will see our characters again though not in reruns. :-)
To the amazing crew and cast, you did yourselves proud in the final season, more so in the final episodes. You went down fighting and you won many life long fans & hearts. Well done to you all.
