I was pretty unhappy with the plot choice made in this episode, at first. It left me cold.
But now I'm extremely curious to see how the show handles things in the aftermath and beyond. I do enjoy how these writers aren't afraid to get themselves into knots and then figure out the consequences - the way they tore things down by starting Florrick/Agos was exciting and a real invigoration of the show. On the other hand, we all saw how things turned out when we finally met Kalinda's husband. Still, they managed to write their way out of that one too, so if anyone can make this new scenario work, it's these guys.
Or this could be the bit where The Good Wife jumps the shark.
