Bad news often comes after hours on a Friday and so it was for TNT's King & Maxwell, which was cancelled after one season. The news is hardly surprising, with episodes still left to air TNT stopped mentioning it in its ratings PR.
Its ratings weren't great, but they weren't "look away" bad either. It premiered to 3.52 million viewers and a 0.6 adults 18-49and closed its run on August 13 with a very similar 0.6 adults 18-49 rating and 3.50 million viewers.
can (and of course will) cry that the show lost a third of its Major Crimes lead-in! That's true and didn't help King & Maxwell's cause any. But it's worth noting that Perception has worse retention out of Rizzoli & Isles but has managed to hang around around (albeit with better ratings than King & Maxwell).
I suspect what probably sealed the show's fate is that the was produced by CBS Television Studios which doesn't have the reputation for wheeling, dealing and discounting just to keep stuff on the air.
Franklin & Bash is the only TNT show whose fate still hangs in the balance.
