    Castle: The Best and Worst Episodes of Season 4 (Thus Far)

    Will tonight's season finale finally make good on all those wayward half-glances and repeated bouts of unspoken jealousy? Or will we be left dangling until next season? In anticipation of the big finish, let's look back at the season's best…

  • Episode Summary

    • 40s jazz club

      This was the most creative episode ever. Nice job writers!
    • So good I had to watch it twice.

      Nothing says how good an episode is than to hear that it was so good it had to be watched more than once. This has to be the best episode of the past 2 seasons. I loved how they would flash from past to present & the dialog was fit for an Emmy.
    • nice one

      one of the best episode in the show
    • Flashback

      This is one I've been waiting a long to happen and my wait has paid off in full, this is another of my favorate episodes of the show. I'm a fan of the noir genere it was one of the first generes I ran into when I was a kid so this episode was a treat for me. It does the same thing as the "Flashback" episode "Magnum P.I." once did where they take all the key characters from the show and transition them into the 1940's decade where the Noir/Mystery genere was born, and it fit like a glove for "Castle".

      It was just great seeing the setting, the common cleches like in one scene Castle states that the couple fell in love in just five days, I find that funny because it's true the couples in most Noir stories always do. But it was just a joy seeing both Kate and Castle in the contemporary roles of the genere, I like how there were different but slightly the same at the same time.

      Castle playing the hard boiled detective doing the narration as things happen down to his charisma. And Kate playing the femme fatale, a beauty that you can't help but fall in love with, mysterious, seems to be a good girl just mixed in with danger. The chemestry with the alternate versions of Castle and Kate is great and strangely found myself carring because it just simply feels right you want both of them to make it. I also can't help but feel that it's also kinda a forshadowing as to where the relationship of both Castle and Kate will head in the future once we find out what happened with the alternate versions.

      Sometimes the future can be found in the past.moreless
    • Great, good fun!

      Everyone involved in preparing this feast for the lovers of nostalgia positively outdid him- or herself. Writers, actors, musicians, producers, photographers, and editors of all facets obviously operated at the top of their form, and probably had a rollicking good time doing so.

      Lanie the sensuous nightclub singer, Ryan the plucky Irish mobster, Esposito the silken Cuban tough guy marvelous. Alexis the brightly malevolent avenging Fury with the southern accent, Martha the bossy, almost-motherly secretary with the New York twang superb (and obviously savoring every second of breaking their previous molds in such a witty and delightful fashion). As the series has progressed, we have seen each actor portray an impressive range of emotions; we already knew that they excelled at bringing their characters to life but we've seldom seen them having so much fun in the process!

      Beckett and Castle, fluid as their characters can be, threw themselves into their 1940s roles with readily noticeable zest hard-boiled detective is PERFECT as a doppelganger for Castle the novelist, his multiplex awareness already established: even in the midst of action, Castle is watching himself AND writing, mentally, the narration of that action. The lovely, magnetic woman of mysterious depths, with a touch of tragedy, blooms naturally from the woman whom Beckett already is, and blends well with the woman she is becoming as she gradually lets down her many barriers and allows herself care for Castle.

      Although the plot itself contained several "guessable" twists, the overall conception and the manifest talents of the ensemble cast made this episode among the most thoroughly delightful of the series to date. Encore!

      • Castle: (talking about what he read in the journal about the secret safe) It happened backstage, right upstairs. They were stealing a moment together, which was dangerous because she was Dempsey's girl. As they stared into each other's eyes, Kate's heart quickened...
        Kate: Did you just say Kate? Are you picturing the PI as you and me as a gangster's moll?
        Castle: What?! No! And I didn't say Kate, I said fate. Fate's heart quickened. I was being poetic. God. Anyway...

      • Beckett: And?
        Castle: And...that's it. That was the last entry in the diary.
        Beckett: What do you mean, that's it? What happened to Joe? What happened to Vera?
        Castle: I don't know.
        Beckett: Well, why would you tell a story when you don't know the ending?
        Castle: If you wanted a beginning and a middle and an end, I have 27 novels you can choose from.
        Beckett: Ugh!

      • Castle: Um, Beckett? Can I take this home for the night? I mean, it might be the key to what Stan was looking for.
        Beckett: You just want to read it because you think it's cool.
        Castle: Yeah, well, that, too.
