Harry's Law

Can anyone please let me know what happened to this great show? A few days ago, I discovered it and watched season 1 within only 2 days; I was simply hooked. A charming, touching and funny show with an incredibly great Kathy Bates. Finally a show again that I really loved, some parts even had what I call "West Wing"moments.

And now - this is essentially a completely new show where they have left the two main characters, but changed every possible aspect of it, including the wonderful soundtrack music. I mean it is still quite good, but just your average lawyer show just the same as they have been produced for the last 30 years. Any explanation for that or a reaction from the network?
