I can't believe they killed "The Unit"!. Granted, a pretty consistent third isn't the greatest, but a (Sunday night) 3+ share in the demo and a typical 80% retention out of "Cold Case" should have been enough to keep it around.
That's a real Bummer!! to you Eye-net!
You can sorta make it up to me by picking-up "Medium" though ;D
You're right that the ratings were good but The Unit's ratings were down and unfortunately CBS can't keep every show around. The budget was pretty high too. The show probably would've been kept around if it aired on NBC, Fox, or ABC but the bar is higher for CBS>
