This series is quite good, yet unfortunately it isn't that awesome like claimed by the most reviews here. The cast is attractive but good acting wasn't the priority in hiring. It is a big plus that there is a background plot. The cases of each episode aren't really good written and they try too hard to be heartwarming, sometimes it is even disgustingly sweet.
I rated it with five stars after watching all seasons completely because it is easy going and helps to get the illusion of a better place.
But if you are interested in court related series I strongly recommend The Practice and Boston Legal, maybe Ally McBeal, too. All of them are more trustworthy than The Good Wife.
Without the name Ridley Scott and lots of popular actors (all of them have seen better days) it would have been less than five stars.
