Been binge watching The Good Wife after never having seen it. It was really good for the first few seasons. But it’s pretty obvious it went through some turmoil starting when they hire Jason Mara, and then dump him a couple of episodes later.
Then it starts going in circles and spirals into a horrible storyline in season 6 that gets completely undone by the end of the season. What a mess. I have to wonder what happened behind the scenes. Were the showrunners spread too thin? Did the network meddle in it?
Can't speak to overall issues, and haven't watched it since it originally aired, but there was somewhat infamous friction between Julianna Margulies and Archie Panjabi, to the point where they would not appear in a scene with each other. The scene in the final episode (or near it, I don't exactly remember) in which they appear together at the bar is assembled from separately shot footage.
I think it mostly suffered from the standard network TV show issue of not having a real plan beyond "as many episodes as possible".
