Apparently I NEED to Start Watching Castle

Castle is one of those shows I was interested in, watched the pilot, and knew I'd probably enjoy it, but then I refused to commit.

Now, I regret that. Not only have a number of people told me I would enjoy the show, but it would appear that Nathan Fillion (love him) has given a special shout out to his Firefly fans in the Halloween episode that aired last night. I'm sold.
