With the WGA writers’ strike ending, the hope is now for the SAG-AFTRA actors’ strike to be resolved pleasingly, and then the shows we all know and love will come back. Amongst those on hiatus for who-knows-how-long is "Blue Bloods," which will kick off Season 14 when it returns, after CBS took a while to renew the long-running cop procedural earlier this year.

It's been cancelled and I'm glad. Now I wish they would do the same thing to Elliot Stabler and Voight from Chicago P.D.

Danny is way too young to retire, even with Blue Bloods ending. Now Frank is definitely at retirement age.
