As pleased as I am that Castle ended when it did (although I do miss it!), I'm wondering: how badly do you figure ABC wishes it had gone forward with S9 right now? I just saw a 0.6 for Agents of Shield, and with Conviction and Notorious dead, and Secrets & Lies on its way out, too, the entire drama section of the network is just going to be Shonda Rhimes soon.
It kind of depends on which part of ABC you are looking at, I think. The ABC network probably doesn’t miss the show that much because by the time season eight rolled around it was nothing but trouble for them and the ratings weren’t really paying off with advertising dollars at 1.0/1.1/1.2 which is what the network really cares about because that’s how they make their money. I do think they are missing the reliability of the Castle fandom because you never really had to worry that we weren’t going to tune in week after week, and they also would love to have a drama still going that wasn’t from Shonda Rhimes and/or Shondaland, as well as something that saw a significant kickback in delayed ratings like Castle did in its final two seasons.
ABC Studios, on the other hand, desperately misses Castle. Castle made the studio more money than any other drama in over a decade, solely because of its popularity in foreign countries and the number of syndication deals. For the studio, that’s a huge chunk of change that they are going to lose, and they would take all of the headaches, frustrations, and what have you to still have it in production.
I do think that ABC (the network) regrets maybe not taking care of Castle and letting things deteriorate until there was no saving the show under its original premise. But maybe they’ve learned a valuable lesson and the next show that comes along won’t suffer the same fate.
