Five Things I Think I Think (January, 2026)
It’s been quite a while since I’ve shared some Things I Think. Since I just jumped back down the Castle rabbit hole, and finished off the associated Nikki Heat books, I had the basis for this column. And away we go!
Nathan Fillion was a big name on the nerd convention circuit (you know I was a nerd way back when it got you laughed at in school) due to the cult favorite, Firefly. He’d had some attention in more mainstream things such as Two Guys, a Girl, and a Pizza Place, but in 2009 a buddy cop show launched him to stardom. He was Richard Castle, a James Patterson-like writer who works with NYC detective Kate Beckett (Stana Katic). It’s an odd couple pairing, with the immature Castle constantly annoying the professional driven Beckett.
I like a drama buddy cop show with humor, and Castle is one of the best. There are some over-arching story-lines, and even a big cast change. Humor, original crimes, good cast: this show worked. I’m on season two of my first-ever re-watch, and this is still a favorite show. It holds up, and Fillion really shines. It’s got more humor than his current hit show, The Rookie, which I also watch.
The show ran eight seasons, with viewership trending downward, as is often the case in long-running ones. But it got to where Fillion and Stanic were not even speaking off camera. It was abruptly announced that the show would continue without Katic – only Fillion. Not long after that, it was canceled outright. Several Castle co-stars have appeared on The Rookie. Katic has not been one of them. But you can’t go wrong watching Castle.
