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.

One of the best shows i been watching since day 1. Its a funny and not so serious crime drama show. I think that is the reason why i fell in love with this show. First of all congrats to the great writers, cast, and crew. Stana and Nathan best chemistry on tv and you don’t really find that much now a days. Tamala, Seamus, Jon, Molly, Penny all are great at what they do. I hope that they do not cancel this show because i can see this show going strong for a long time. This is what i do not get which the network, if a show does great why do they either end it or cancel it? why? Well as of today i still get a kick out of watching castle reruns. PLEASE DO NOT CANCEL THIS SHOW!!!!!!!!!!!!! ONE OF MY FAVORITE CRIME DRAMA. THANK YOU.

I’ve been hooked on this show since I first saw it. I have my DVR to automatically record it so I don’t miss any new show or old show. I started watching the show right in the middle and can’t get enough of it! It’s one of the few shows that my husband and I actually like to watch together. My almost 10 year old son (but I won’t let him see how the people were killed or hear anything he shouldn’t) loves the show! Anytime he hears that Castle is recording he gets really happy. He says he wants to be a Cop like Beckett! I love the show it refreshing especially since almost everything else on just doesn’t make any sence or just gives me a headache! I always get caught up watching it and for me that’s a big thing. Please don’t take this show away!!! Last time I got caught up this bad in a show was with the show Charmed, and to be honest I love castle more that it.

Ditto Penny (I couldn’t have said it better):
One of the best shows ever. We have watched every show and look forward to every new show and even reruns. In a world of horrible reality shows this how is so refreshing. Please don’t take it away from us.
