    • what fun:)

      what a fun episode:) The 'mockery' of Firefly. Nathan Stark from Eureka, the principal from Buffy. Becketts enthusiasm for the little known scifi show
    • The Final Frontier

      I give the show praise for trying to think outside the box and have a fun episode at a sci-fi convention, but it was just a really boring story as I did not buy into any of the characters, and could not care what happened to them or who the killer was. The episode just did not suck me in.
    • 5x06 - Epic!

      It isn't often that I give a show a perfect ten rating, but this episode was so good that I have to bestow it. Not only did I spend a lot of my time laughing, I also genuinely enjoyed the mystery and I didn't even call the killer's id like I usually do. Go show.

      The show did such a great job of gently teasing the geekery in the viewer (a total sci-fi geek here!) but it also dished a lot of love not only for the sci-fi genre but also for the geeky fans who love it. I adored that they had Beckett be a mega fan for a terrible show and they backed up her love by explaining why the show had such meaning for her. Something which all sci-fi fans can say, although not necessarily with her level of eloquence. I just loved that!

      I found this a brilliantly funny episode! So many things cracked me up: Castle teasing Beckett over her mega fan status, his freaking out about losing his hair, his shriek of horror over seeing Alexis all dressed up as a sexy assassin (this one in particularly made me pause the show until I could get over my gigglefit); Alexis and Castle 'not talking about it' non-coversation and the last scene!

      I was also surprised by how much I ended up liking Nebula 9's 'Captain'! The man may have been a 'washed up actor' but he clearly loved the role a ton to go out and spend money to get himself a working blaster. It brought a huge grin to my face.

      Great episode! I don't always rewatch this show but I'll happily see this episode again. It was so well done! Now that's the way to make a shout out to fandom!moreless
    • This was a total delight to any sci-fi geek

      This is what I love about Castle, that it gives us lots of quirky and colorful stories and characters. It has heavier material, like the on-going story of who killed Beckett's mother, but for me it really shines when it is being fun and off-the-wall. I especially loved all the meta references to sci fi culture, and in particular Firefly. And it was a good murder mystery, it kept me guessing until the end.moreless
    • Nice one

      A nice trip into the fun side and viewers needed that after the heavy drama in last week's 'Probable Cause'. There were some really funny moments and a few subtle hints of the developing relationship. However, the episode was hyped up a bit too much. We have had better (and lesser hyped) ones this Season. Enjoyed it nonetheless

    • QUOTES (7)

      • Beckett: So I was a Nebula-9 fan. Big deal.
        Castle: Oh, you were beyond a fan. You dressed up in costume. You.
        : Okay, yes. I was a sci-fi loving, costume wearing geek. And you know what? Not ashamed of it or of Nebula-9. Despite what you think, it was an awesome show.
        Castle: Hmm. I'll tell you what. I'll forgive you your terrible taste, if you (Castle eyes Beckett) try on that Nebula-9 costume for me.
        Beckett: In your dreams.
        Castle: Look at my life. My dreams come true.

      • Beckett: Are you saying...
        Castle: She was killed by a phaser?
        Perlmutter: Well, as much as it pains me, Mr. Castle is marginally correct. She was killed by a high-intensity laser beam.
        Castle: A real sci-fi murder, at a Sci-Fi convention. Just keeps getting better.

      • Castle: Tell me, you guys, do you think my hair is thinning?
        Beckett: You're not losing your hair, Castle.
        Castle: Okay, so if I wake up bald tomorrow, you'll still be attracted to me? (Beckett pauses) Oh, my God. You wouldn't.
        Beckett: I didn't say that.
        Castle: No, but you were thinking it. I can see it in your ...
        Esposito: With that pumpkin head? Dude.

      • Beckett: Just goes to show you, sometimes people aren't what they appear to be.
        Castle: For Alexis' sake, I hope you're right, given what she was wearing.
        Beckett: Castle, she is a full-grown woman.
        Castle: Who, as we speak, is being ogled by thousands of sweaty, lecherous fan boys. It's just so ... wrong.
        Beckett: Can I just point out the fact that the costume that she was wearing is not so different from the one that you are asking me to wear?
        Castle: Don't say that! That ... it's confusing and disturbing.

      • Castle: Let's go back to the e-mails of the crazed Nebula-9 fans. And when I say crazed fans, I'm, I'm not referring to you. You ... are a mega fan.
        Beckett: Nice one coming from the guy with a life-size Boba Fett in his bathroom.
        Castle: Point taken.

      • Beckett: Perlmutter.
        Perlmutter: Detective Beckett.
        Castle: Perlmutter.
        Perlmutter: And non-detective Castle.

      • Castle: Perlmutter, good to see you.
        Perlmutter: Ah, if only the feeling were mutual.

    • NOTES (3)

    • ALLUSIONS (3)

      • Castle: Here at SuperNova Con? Shiny.

        Allusion to the western science fiction series Firefly where characters use the word "shiny" when they are excited about something. The series aired on FOX from 2002 to 2003. It was written and directed by Joss Whedon and starred Nathan Fillion.

      • Castle: Let's make sure that history never forgets the name Enterprise.

        This exact line was spoken by Patrick Stewart as Captain Jean-Luc Picard in Gene Roddenberry's television series Star Trek: The Next Generation (1987-1994), episode Yesterday's Enterprise (1990).

      • Castle: I'm a fan of good sci-fi. StarTrek, Battlestar, that Joss Whedon show, but Nebula 9, nah, nah. It's all phony melodrama and lifeless acting.

        That Joss Whedon show alludes to the television series Firefly (2002-2003) by writer and creator Joss Whedon in which Castle actor Nathan Fillion portrayed the main protagonist, Captain Malcolm "Mal" Reynolds.
