Castle Review: Well Done, Sherlock

at . Comments

In the words of Ethan Slaughter: “Outstanding!”

The latest episode of Castle, Headhunters,” chased down a murder between gangs, as well as pairing Castle up with a new partner. A Firefly reunion took place and oh was it fun. Let’s discuss.

Mal & Cobb. Adam Baldwin guest starred as Detective Ethan Slaughter, a no-nonsense tough guy cop who Castle decides to shadow. Nathan Fillion and Baldwin worked together on Firefly and you could absolutely tell. The chemistry between the two friends paid off with a fun hour before we face the end of the season.

Detective Ethan Slaughter

Slaughter is not a detective that I would want to watch every week, but I wouldn’t hate if he popped up here and there to shake things up a bit. He brought some life to the show and placed Castle in a different situation. Not only did Baldwin rock this role, he also delivered some hysterical one liners that you can check out in the Castle quotes page. 

Fillion is nothing but loyal to his long time fans, putting in an Easter egg of his own to go along with the one written into the hour. We got to see the two trade off Mal’s brown jacket and if you looked closely enough, there was a catalyzer placed on Castle’s shelf. Loved it.

Leaving The Nest. Castle decided to branch out and hang with a different detective, stirring some feelings with his usual partners. Even with the bit of jealousy, Ryan and Espo still saved Castle from a bad situation. Beckett seemed to be pretty bothered by the situation, even speaking with her therapist about Rick.

Castle and Detective Slaughter

“You weren’t waiting, you were healing.” Beckett’s therapist returned again to talk some sense into our beloved Beckett. She recognizes that Castle is pulling away from her and that maybe she waited too long. Well, duh! You said it yourself. It’s been seven months. It’s time to make a move before he seriously does move on.

What do we think about this? There are plenty of mixed feelings on the Caskett front. Some fans don’t want to deal with the relationship drama, others are dying for it. I’m on the fence.

On one hand, the writers have done an excellent job of building the friendship between the two lead characters, making the chemistry feel real and understanding the feelings between the two. On the other hand, it’s been dragging on for what seems like forever. Castle has put himself out there and so has Beckett. If it doesn’t happen soon, I won’t expect it to happen till series end. TV Fanatics, what’s your opinion on the Caskett situation?

Side Notes. 

  • Alexis got into some really great schools. Didn’t know I could be jealous of a teenage TV character about college acceptance...
  • Javi needs his own arc and quick. We haven’t been getting enough Espo time in the last few episodes.
  • No Lanie tonight. Kinda sad, considering she played a rather big role in the last episode.
  • Did anyone really care about the weekly case or were you more interested in Slaughter himself? But, how entertaining was the garbage truck scene? I had to look away!
  • Who knew Castle packed such a punch?
Overall, a fun hour that held two reunions - Fillion and Baldwin, and even better, Castle and Beckett. Rick is back working with his real partner just the way we like it. Sad news Castle fans: Only two episodes remain in the season. So hit the comments and predict what is going to happen in the penultimate episode.
Don’t forget to check back for the Castle Round Table later in the week. No episode next Monday, so make sure you take the time to discuss “Headhunters” and the zombies to come to pass the time.

LOVED Adam's rough, tough bruiser cop! He made what might be a pivotal comment to Castle, 'A man gets a woman like that or dies trying'.


Sort of enjoyed this episode but I just keep waiting for Castle and Beckett to tell each other how they feel and it sort of makes you forget what's going on in the show generally. Get them together and then we can go back to the fun show that it used to be. Making them a couple opens up so many avenues for great storylines. Slaughter was awful and as someone else has written a total caricature - if he was a real policeman he would have been sacked by now (hopefully).


AS usual, I loved it like I always does. I am eagerly waiting for Finale, title itself says too much, "Always". :) Of course, everyone know "Always" is Caskett word. :)


yep the general consensus is, and not just on this forum.....
Must admit thought my first thought was to sit on Baldwin and shave that awful haircut clean off. :p


Okay - all this episode made me do was miss Captain Malcolm Reynolds. I love Nathan, and I love Richard Castle, but Richard Castle is no Captain Reynolds. And it also made me miss John Casey from Chuck. I still mourn for those shows... That being said, the man they call, Slaughter...was compelling, and his interactions with Castle were gold. Baldwin and Fillion just work. It was a good reminder that the show is called CASTLE, not Caskett. Speaking of Caskett - seven months, and she was healing?!?! Nah, she was hiding. Get. a. move. on.


did anyone else notice the "reservoir dogs" nod - or was I making it up?


3 words! Best show Ever!!!


I loved this episode. It was awesome! Loved the Slaughter character. them working together again was great. But i do still love the Caskett scenario. Cant' wait to see what is going to happen with them. Love them together. I don't get why everyone is such downers about shows that have some actual entertainment. I wish they would get rid of all these crappy reality shows that are so not worth my time watching. Castle is one of my favourite shows and always will be. so entertaining, I love it.


Well I just watch the Show again ( I tape them) And I can Stop them and go back and watch something again. And I did miss a lot. Now first Castle was right Slaughter is insane He almost get himself and castle killed if not for Ryan and Espo coming to the rescue. now Beckett see's her therapist and the last thing he says is what do you want to do? Now Beckett,Ryan and Espo have been working on the case and when Castle says no to Slaughter and goes to Ryan for help he tells him to go to Beckett and She hands him the file now they go to the crime scene and they figure out why he climbed the fence to get to the phone to call his Dad for help they check what calls were made from that phone and they get the Killer like they always do and at the end He says thank you to her she had put Her job on the line for him. She says thats what partners do. Now that line says it all her Therapist said what do you want to do?He now knows she always had his back and they are much closer. and now She is going to do it right watch the next show and see the differents.


I didn't care for last night's episode. It was too CAVEMAN for me. Besides, Kate and Castle were hardly shown together--which is why I watch the show. One of them (I actually don't remember which one!) was on a talk show recently and gave the impression that the two were getting together soon--so why is it taking so long??
Also, I'm not that fond Castle's family--his mother is kind of a caricature, and his daughter is way too perfect.
