Tonight marks the end of The Astronaut Wives Club TV show on ABC — at least for now. The network has yet to officially cancel or renew the series for a second season. How’s the show done in the ratings? Should it come back or did tonight’s finale properly end the series?

Based on the book by Lily Koppel, The Astronaut Wives Club focuses on seven women who were key players behind some of the biggest events in American history. As America’s astronauts were launched on death-defying missions, the lives of their young wives were transformed — seemingly overnight — from military spouses to American royalty. The cast includes Yvonne Strahovski, Dominique McElligott, Odette Annable, Joanna García, Erin Cummings, Azure Parsons, Zoe Boyle, Bret Harrison, Aaron McCusker, Wilson Bethel, Kenneth Mitchell, and Desmond Harrington.

The show debuted in mid-June to a 1.1 rating in the 18-49 demographic with 5.51 million viewers. That was a mediocre start. The demo was pretty low but total viewership wasn’t bad for a summer series.

Unfortunately, both the demo and general viewership took a big tumble in week two — and the numbers fell much lower as the season progressed. Last week’s installment matched a series low in the demo (a 0.6 rating) and hit a new low in viewership with 3.2 million.

Looking at the network’s summer ratings, Astronaut Wives Club has been performing about the same as their other scripted fare — The Whispers, Mistresses, and Rookie Blue. None of them have been doing very well but the network needs some scripted shows to air during the summer months.

Based on the ratings, it seems like ABC should cancel Astronaut Wives Club and let the story end with tonight’s finale. However, they certainly could decide that it’s worth give a second round next summer.

But, what do you think? Do you like The Astronaut Wives Club TV show on ABC? If you ran the network, would you cancel it or renew it for a second season? Was tonight’s finale a satisfying conclusion to the series?
