There’s a clip in the opening credits for Castle where Nathan Fillion catches a glimpse of himself in a store window and exclaims, “I really am ruggedly handsome, aren’t I?” Why, yes, Mr. Fillion, you are. I may have come late to the party–never having watched Firefly and only picking up Castle recently, but I play a mean game of catchup thanks to streaming Netflix. If Nathan Fillion is anything like either Captain Mal Reynolds (a confident risk-taker) or Rick Castle (a clever rogue), then his ruggedly handsome self is welcome wherever, whenever.
