    Please don’t cancel Castle. I love the chemistry between Castle and Beckett. The whole cast are good actors.

  2. Susan says

    Please don’t let Castle be canceled. Let Beckett get pregnant and let the shows continue on. I love his mother and daughter, they give a lot to the show also. Everyone in the show is great. Please continue on with this show.

      Castle is still a lovely series and has been very well written. However, the thrill of ‘will they or wont they’ has gine I am afraid. The story lines are still very well thought out but sadly no writing can replace that excitement. Therefore, unless sonething radical happens I can see the series slowly being withdrawn because the ratings have gone down and sadly will continue to go down.

    It looks lime my two favorite shows are being canceled. It makes not really care if I even have a TV. I am so hoping that Castle and Bones will be saved.

    Castle is just a wonderful series full of clever detective stories and a wonderfully evolving romance mixed with very good screen writing.
    I live in London UK and can’t keep my hands off the dvd box set. This is the best detective duo since Moonlighting in the 80’s and best here since Bergerac.

    Please please never stop making them as there so entertaining. The only series I would say is on a par in the UK with Castle is Sherlok.

    All the best
