Are you sure? Fridays are usually a death sentence. It's like the last move before cancellation for most shows!
I wish they gave Kalinda more air time! She's getting a bit more as of late but at the start of this season she was barely in it.
For a show like The Good Wife, similar to Blue Bloods, it skew very old but has a small but solid key demographic. Obviously, on a Friday, you have lower expectations. That way, it can continue to air on CBS with low ratings and continue to give CBS the critical acclaim and awards.
