ABC’s ‘Castle’ season 8, episode 6 review: Adam Baldwin, Nathan Fillion make ‘Cool Boys’ cool

Castle -Castle” and its writers had a tough challenge laid out for them Monday night: Tell a compelling, interesting installment, and do so without one of your main stars. Stana Katic was MIA for “Cool Boys,” and yet the show managed to pull off something that stood on its own two feet. We don’t want to see this happen often (or really the rest of the season), but this was even more fun than we thought it would be going in.

Much of the reason for the story’s success comes down to a certain guest star in Adam Baldwin. The former “Firefly” actor obviously has that tie with Nathan Fillion, but the writing played very much to his strengths: Aggressive action sequences, but then also lighter moments where he can play a little bit against type. We learned a lot about his Ethan Slaughter character tonight, including that he was married to a famous opera singer and that he majored in musical theater in school.

Is this the sort of thing that merits a return appearance from Baldwin? Sure, eventually. We know that he is busy on “The Last Ship,” but we’d love for this to be an annual gig for him. (Granted, it’s possible that there may not be a ninth season.)

We admit that the case itself was somewhat flat when it comes to the circumstances and the events. Ryan and Esposito got a chance to be the shining stars of the crime-solving, but we enjoyed them more bouncing off of Slaughter and Castle than forcing the perp to make a confession. We’re not really going to remember that mystery in this episode at all; instead, we’ll remember Fillion and Baldwin singing show tunes, Ethan cooking, Ethan meeting Martha, and also Rick attempting to cower away when Slaughter showed up at his office. Also, Ethan at the end of episode tried to use Castle’s connections with the Mayor to do his bidding.

In the end, cool boys was … pretty cool. We didn’t know what to do with an episode sans Beckett, but at least we laughed often, and there was a nice moment when Ethan handed down some advice to Rick at the end: Don’t let Kate go through her struggles alone. Find a way to make her needs the priority. Hopefully this will apply to the story moving forward. Episode Grade: B.
