“And if you want to be invited into my territory again, you might want to re-think that.” – Kate Beckett. To be honest, I wasn’t completely thrilled with “A Murder is Forever,” but it was certainly a big step up from last week’s “Like Father, Like Daughter.” I won’t even light that fire again. Although “A Murder is Forever” has a lot of things going for it, including a few good Castle (Nathan Fillion) and Beckett (Stana Katic) scenes, one huge action-packed interlude, and an overall twisty murder investigation, however there are a few things that fell flat for me.
