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.

Absolutely WORST show on TV – BORING CAST! Take it off and leave the decent shows on for a change..

Castle is one of the very few shows I watch and record because most of what is on is so fake, stupid and mind numbing. Castle is entertaining and fun. Why is it they keep the, pardon the expression, crap, and get rid of the good ones? If they cancel Castle, that leaves only two non news programs for me to watch on a committed basis.

I agree with the other posts. Please do not cancel this show. It is very entertaining and both me and my 2 girls love to watch it. We are hooked on it. We even watch the reruns on TNT almost every afternoon after school and homework is done. This show has everything that we like in a show, comedy, drama, and it all works together. It is so very entertaining. Also the show “Bones” is the same way, so please don’t cancel either one of them.

The 6 season was good fun,lots of different twist an turns,having us on the edge of our chairs. This show deserve to continue for many seasons,because the writing is so so good,and there are lots of stories to be told. Both the cast and the crew is doing a stellar job
There ought to be a lot more publicity about this show,to make it even more known around the world,that it really deserve.

This is a light hearted, easy to follow and can be very funny. Wonderful actors for great characters. Each show has a petty good plot and I love that old time slap stick comedy. When you consider other shows that are on, this one seems to have it all. Sometime funny. sometimes serious, all with a love story. Keep this one around we need more of them to get our minds off of all the other things going on.

I hope Castle isn’t cancelled because I love this program, and the same with Bones. There are so few decent shows on t.v. now. Most shows are disgusting. I find these two shows very interesting, with a little of everything; suspense, romance, comedy, and they are not dirty.

don’t you dare take Castle off the air. I look forward to this show every week and plan on purchasing the whole castle series. I will hunt you down like a dog if you take this show off the air. it is one of the few shows with quality left.

This is one of the most entertaining shows on TV. It combines drama with romance , a truly excellent combination. I tell everyone about this show and they love it.
NEVER cancel it.


Liz June 10, 2014 at 12:08 am

I have just recently started watching Castle in re-runs on TNT. I hadn’t really known anything about it. I believe it needs more advertising and a different time slot on ABC. Please don’t cancel it. It has become my second favorite show on television. I wish I had discovered it earlier.

What is the brand and color of the lipstick that Kate Becket wears on the series? I am a fan and hope it’s not cancelled.
