Who was the Episode MVP ?

  • Plot Line Didn't make Sense

    The plot didn't make sense like it usually does. The guilty characters acted completely normal for the entire episode, and then became psychotic or guilty out of the blue. This makes the plot weak, as they were criminals of convienence. Other than this, the episode was ok and didn't have much in character development for the usual cast.
  • this episode the disaster happened not buy accident but on purpose this episode had a cool story line the graphics and special effects in this episode was very good .

    Kennywood Park is located in downtown Pittsburgh , Pa. The rollocoaster Grissom held the record for(The Steel Phantom) was replaced a couple of years ago with The Phantom's Revenge . It doesn't go upside down like the previous coaster . this was a great episode about rollercoasters and the work that goes into them . roller coasters are dangerous if not kept up but in this episode the disaster happened not buy accident but on purpose this episode had a cool story line the graphics and special effects in this episode was very good . this was a good episode.

  • Grissom looking for a screw!!

    So this episode was great. It gets such a high rating due to its comedic value. Catherine and Warrick's case wasn't overly good but it wasn't the worst B plot in the history of B plots. It had so much GSR I don't know where to begin.

    I'll start with the greatest quote in CSI history. Grissom is looking for a screw. Now I know what he *actually* means but the way I interpret it is much better. What made that quote even better was the fact that he was talking to Sara when he said it. I think that this is a quote that should win the award for best CSI quote ever. What also was great about the episode was the fact that Grissom and Sara worked comfortably with each other the entire time. Overall a great, funny episode. (I wonder how many times I used great in this review.)

Trivia, Notes, Quotes and Allusions


  • TRIVIA (2)

  • QUOTES (12)

    • Nick (after seeing two teens have sex on the roller coaster): Well, so much for safe sex!

    • Nick: Well, there goes my theory. No one tampers with their sex machine.

    • Greg: I found something a little unusual for a roller coaster. Not a sailor but a...
      Sara: Semen. Sex on the roller coaster?
      Greg: Or some kid shaking hands with Shorty.
      Grissom: The release of epinephrine and adrenaline while riding a roller coaster can produce a stimulatory effect. It enhances ejaculation.
      Greg: Right.

    • (Ms. Press just confessed she killed her own daughter)
      Ms. Press: Justin was the best thing in my life.
      Catherine: No. Your daughter was the best thing in your life. (Catherine gets up, disgusted, and heads for the door)
      Ms. Press: You didn't know her.
      Catherine: I do know that she was 13. A child. (walks out the door)

    • Woody: Oh, I just hope they don't blame the coaster. It may not be the Manhattan Express at New York, New York or the Desperado in Primm, but it-it... it still makes grown men scream.
      Grissom: My first week in Vegas, I rode the Desperado.
      Woody: My first coaster marathon. I rode that monster for a week straight.
      Grissom: Hmm. The Steel Phantom, Kennywood Park, Pennsylvania -- I actually hold the marathon record there.
      Woody: Uh, uh. My-my favorite's still the, um, Kings Island. The Beast.
      Grissom: Mm. I presented a paper at an entomology convention in Cincinnati just so I could ride Son of Beast. Head over heels on a wooden track.
      Woody: Ah. So, you prefer wood over steel?
      Grissom: No. Not really. For me, it's not about the track. (smiles) It's about the thrill.

    • (After Sara, Nick and Greg arrive at the crime scene)
      Nick: Hey, sorry we're late. There was a news van blocking the entrance.
      Grissom: This is the first time a roller coaster has derailed in Clark County. Huge criminal and civil liabilities issues, so keep it quiet. Photograph the scene. Bag and tag the detritus. Forklift anything bigger than Greg. We're going to put up a tent on the other side of the parking lot for crime scene reconstruction. Questions?
      Greg: Yeah. What's that guy doing so far away from the others?
      Grissom: Curious, isn' t it? (walks away)
      Greg (to Sara): So when he asks if anybody has any questions, he's not really asking?
      Sara (smirks): Well, I don't know much about roller coaster accidents but in auto collisions, the victims found furthest away from the cars weren't usually wearing a seat belt. That'd be my bet.

    • Grissom: "There are three things in human life that are important. The first is to be kind; the second one is to be kind and the third one is to be kind."
      Sara: Henry James.
      Grissom: Very good. Author of one of the greatest horror stories ever written. Turn of the Screw. And I'm looking for one.
      Sara: A screw?
      Grissom: Yes.
      Nick: Oh, well, technically these are eccentric shafts, not screws. (Greg hands him a container full of screws)
      Grissom: Well, as long as you can screw a nut on it, it's a screw.
      Sara: Turn of the Screw isn't really a horror story it's more of a mystery. Did the governess kill the little boy or did the ghost do it?
      Grissom: Well, it's only a mystery if you believe in ghosts. (Sara gives him a look. He holds up a screw) End threads are stripped.
      Nick: Means the nuts were loose. Excessive play on the screws would have worn down the threads.
      Grissom: And the nuts would have popped off.
      Greg: Nuts just don't pop off by themselves. (Grissom gives him a look)

    • Grissom: Everything is relevant Greg, until it isn't.

    • Brass: What kind of training do you get?
      Joey: I release the brake. I hit the button. It's green. It's marked "Go".

    • Nick: Oh, I am the man!
      Grissom (rounding the corner): Are you?

    • Hodges: Your killer has a rash.
      Sara: And we need to catch it.

    • Grissom: Albert... dead men don't ride roller coasters.

    • The rollercoaster/murder weapon is 'portrayed' by The Screaming Mummy at Pharaoh's Lost Kingdom in Redlands, California.

    • This episode was originally titled "A Turn of the Screws" and then "A Screw Turned Loose" before being titled "Turning of the Screw". After going through so many titles, they decided to stick with the original (but dropped the "a") and titled it "Turn of the Screws".


    • The Manhattan Express rollercoaster is located at the New York, New York hotel and casino. Which is located in Las Vegas, it's actually on the strip.

    • The Desperado is located at Buffalo Bill's Casino and Resort in Primm, Nevada. Just outside of Las Vegas.

    • Kennywood Park is located in downtown Pittsburgh, Pa. The rollercoaster Grissom held the record for (The Steel Phantom) was replaced a couple of years ago with The Phantom's Revenge. It doesn't go upside down like the previous coaster.

    • Lisa Hunt/Cleopatra: Five years ago when I was a pre-frosh, he was my Jordan Catalano.

      Jordan Catalano was the object of a high school crush by Angela Chase in the critically acclaimed, but short lived series My So Called Life.

    • The Beast and Son Of Beast are both located at Paramount's Kings Island just outside Cincinnatti. The Beast is the longest wooden rollercoaster in the world, built in 1979. While as the Son of Beast is the tallest, fastest, and only looping wooden rollercoaster in the world. As the park's name suggests, both CBS and this park are (at the time of initial airing) sister companies, creating fewer legal hassles in mentioning the rides by name, not to mention some shameless self-promotion.

    • The name of the park's ride mechanic, 'Woody', is also a colloquial term for wooden roller coasters.
