The ratings for "Castle" have been dipping as of late, and the holiday episode of the police drama was the lowest-rated episode in series history. With the two main characters finally together after four full seasons, it is time for the creators to close loopholes in the series and explore characters that have remained in the background for too long. Here are the top four characters who need to be explored more before the "Castle" series finale.
Jim Beckett
Kate's father, Jim Beckett, has made a handful of appearances on "Castle" but has never been explored. In a recent episode, a friendship began to bud between the detective's father and Rick's mother Martha. The stage was set for further interaction between the two, but the tertiary plotline has not yet progressed. To this point, Jim is only portrayed as a worried father who does not want his daughter killed like his wife. The father of a main character needs to become more three-dimensional.Captain Victoria Gates
The creators of "Castle" toss Captain Gates out of her office from time to time to remind viewers she is there. With a season-and-a-half under her belt, the character portrayed by Penny Johnson Jerald has only opened up a few times. While fans know she has a family and likes collectible dolls, she is only portrayed as a tough boss who will occasionally allow her detectives to bend the rules. Her motivations and past are unknown, and the lack to character depth steals from her overall impact on the show.Jerry Tyson
The serial killer known as 3XK or the Triple Killer is supposed to be Richard Castle's antagonist, but he has made very few appearances. With the show apparently winding down, Jerry Tyson needs to become a sharper thorn in the writer's side if he is going to become a memorable antagonist. Instead of popping up once a year, he should be given a few upcoming episodes to truly drive Rick crazy.Dr. Sidney Perlmutter
Perlmutter is one of the most interesting background characters on the show. His wisecracks to Castle and his inability to show any type of compassion for the dead come together to create a character who needs to be granted a backstory episode. One episode of "Castle" should be dedicated to explain why he is the way he is and why he has so much disdain for the main characters.
It is time to bring characters out of the background and into the limelight before the series comes to an end.
