Bill Nighy is of course the life and soul of any film, or series, he is in; and this is no exception. You know what I mean. I don't have to fail at describing what makes him Great. He looks stern, then he does that secret smiling-thing, then he twitches a little and [insert illustrative hand gesture that starts abruptly and then moves fluidly to the right (both hands)] flows away. And he dances. And he wears a captain's hat at one point.
