Castle: Season Six Ratings

Castle TV show ratingsThe ratings for Castle have been coming down over the last couple seasons. Will they keep falling? Could the show end up being cancelled or is it almost sure to be renewed because of syndication profits? Stay tuned!

On Castle, Rick (Nathan Fillion) and Kate’s (Stana Katic) relationship continues to evolve while they continue to solve crimes. The show also features the talents of Susan Sullivan, Molly Quinn, Jon Huertas, Tamala Jones, Seamus Dever, and Penny Johnson Jerald.

The ratings are typically the best indication of a show’s likelihood of staying on the air. The higher the ratings (particularly the 18-49 demo), the better the chances for survival. This chart will be updated as new ratings data becomes available — usually the next day, around 11:30am EST/8:30am PST. Refresh to see the latest.

    PLEASE RENEW CASTLE . . . I have been addicted since season 2 and watch all of the reruns on TNT – EVERY DAY!!!
    The show is amazing and the chemistry between Kate & Rick just makes my week complete! I have ready every book from every season, ordered coffee mugs, clothing and other souvenirs from ABC along with EVERY season!
    I would love to see more about the “Old Haunt” that Castle bought and see more of Kate & Castle in the Hamptons . . . his little mansion on the beach.
    PLEASE, PLEASE, PLEASE listen to your viewers that voted this the best People’s Choice along with Stana and I was shocked that Nathan wasn’t a nominee this year!
    Thanks for considering my request!!!!!!!!!!

        I’m in an older demographic; but truly enjpy Castle. Our taste should be considered since we spend too. Please don’t cancel Castle.

    Excellent writing. The writers have created a set of characters that keep me waiting. If the show is cancelled, and I hope not, the marriage of Castle and Beckett needs to be aired. I am in the older bracket and do not watch any shows live. I stream Castle and all the shows I watch through Amazon. I dislike watching 18 minutes of commercials on any show.

    Streaming lets the watcher catch all the moments that most miss watching it live. There is much humor that flashes by and once you see it again, so much is revealed.

    I have watched castle for six seasons. It is a show that appeals to all ages. I AM NOT THE AGE OF 18_49 but feel ratings should check other ages . GReat show. ABC needs to promote it more. Let’s see more appearances on talk shows of the actors. WHEN I HAD A CASTLE BUMPER STICKER ON MY CAR SEVERAL PERSONS CAME UP TO ME AND THEY SAID THEY LOVED THE SHOW AND ONE PERSON EVEN TOOK A PICTURE OF IT. PROMOTE THE SHOW AND AND KEEP IT GOING !!!!!

    Castle is the ONLY show that I currently watch on ABC. It’s a fantastic show and if you cancel it, you would be hard pressed to find it’s equal.

    Let me just say KEEP CASTLE ON
    The reason being.The stories are grate,the actors are grate.They manage to keep it light
    even if the stories are serious.Somehow I don’t think people would have woted
    Them the best crime show during PCA.Not to speak about Stana Katic
    who got a well deserved PCA herself. Think of all the good stores there is
    Of course it should be re-newed ..
