[[quoteright:214:https://static.tvtropes.org/pmwiki/pub/images/Hawaii_Five-O.jpg]]

* {{Fanservice}}: It's a show set in Hawaii. What do ''you'' think? (Not to the extent of the new show, mind you.) Although the directors can be [[MaleGaze drawn to some of the female guest stars]] -- witness the loving shots of Kathleen (billed as Kathy) Beller in "The Waterfront Steal" -- and most of Simone Griffeth's camera time in "A Very Personal Matter" ''screams'' this trope. Season 12's "The Kahuna" provides a rare case of equal opportunity fanservice with Kimo and a HotScientist played by Cathy Lee Crosby [[ItMakesSenseInContext stripping down to skivvies to go diving while looking into mysterious deaths]]. And they don't waste any time getting Maud Adams into a skimpy bikini when she turns up in "Deep Cover" [[spoiler:as a FemmeFataleSpy after tech info for the KGB.]] Creator/SusanDey spends a good deal of "Target -- The lady" in BareYourMidriff mode.

* ChekhovsBoomerang: "One Big Happy Family" [[spoiler: In this case. It's more like Chekhov's Phone Book Cover; the ''only'' crime Monica Ferguson is commits is stealing a phone book cover from the hotel the family's staying at.]]

* BadassBolas: In "Though the Heavens Fall", a vigilante group use bolas to capture the criminals.

* DrivenToSuicide: [[spoiler: "Up Tight," "To Kill or Be Killed," "Death With Father," "Is This Any Way To Run A Paradise?", "I'll Kill 'Em Again." The beginning of "Invitation to Murder," and "Small Potatoes." "One Born Every Minute" and "Murder Is A Taxing Affair."Dominick Vashon in "V for Vashon: The Patriarch."]]

* TruthInTelevision: When August March (the BigBad in "Wooden Model Of A Rat") is held and gunpoint and told to reliquish his weapon, he puts his gun in the floor ''slowly and carefully''. Casually tossing aside a loaded weapon in standard movie/TV fasion is a great way to ensure it discharges on landing and possibly shooting yourself.

* TitleDrop: "Strangers In Our Own Land," "One for the Money," "Just Lucky, I Guess," "A Bullet for [=McGarrett=]," "Why Wait Till Uncle Kevin Dies?" and "The Last of the Great Paperhangers" all work their respective episode titles into the dialogue.

* NotSoDifferent: The whole point of the 1969 episode "[[ExactlyWhatItSaysOnTheTin Not That Much Different]]".

* InfantImmortality:
** Averted in "The Listener," in which a psychiatrist is targeted by a man who's bugged not only his home but his office -- the villain averts EvenEvilHasStandards by among other things playing a young boy a taped conversation between the doctor and the boy's mother, where she reveals he has a fatal brain tumour. The doctor tells the boy the tumour is shrinking... and later tells [=McGarrett=] that the boy really ''is'' dying.
** Also averted in the two-parter "Once Upon a Time", where [=McGarrett=]'s sister is in thrall to a quack doctor who claims she can cure her baby, who has cancer. The child passes away long before the end of part one.

* JurisdictionFriction: McGarrett arrests Jack Fabian for the murder of an HPD cop, but Federal Agent Al Marsh wants Fabian to turn evidence against the Syndicate and is willing to offer him immunity from prosecution.

* SplitPersonality: [[spoiler: In "Bomb, Bomb, Who's Got The Bomb?", a senator is being terrorized by a bomber. Unknowingly, ''he's'' the bomber -- because he accidentally shot and killed his own father as a boy and has never forgiven himself.]]

* {{Fanservice}}: It's a show set in Hawaii. What do ''you'' think? (Not to the extent of the new show, mind you.) Although the directors can be [[MaleGaze drawn to some of the female guest stars]] -- witness the loving shots of Kathleen (billed as Kathy) Beller in "The Waterfront Steal" -- and most of Simone Griffeth's camera time in "A Very Personal Matter" ''screams'' this trope. Season 12's "The Kahuna" provides a rare case of equal opportunity fanservice with Kimo and a HotScientist played by Cathy Lee Crosby [[ItMakesSenseInContext stripping down to skivvies to go diving while looking into mysterious deaths]]. And they don't waste any time getting Maud Adams into a skimpy bikini when she turns up in "Deep Cover" [[spoiler:as a FemmeFataleSpy after tech info for the KGB.]]

* VillainousBreakdown: Subverted in "The Miracle Man" [[spoiler: When the Reverend Andy is tricked into broadcasting to his waiting audience that he's been taking his faithful for all he can get - as well as sleeping with assorted attrsctive Sisters of his crusade; it's a subversion because he's not guilty of ''any'' crimes in the eyes of the law. But now everyone knows what Sister Harmony learned - "(he's) a liar, and a hypocrite!" Reverend Andy goes to pieces as the audience walks out the auditorium.]]

* TheBadGuyWins: A few times, but probably the most galling was in "The Jinn Who Clears The Way". [[spoiler: McGarrett has Wo Fat dead to rights for murder, grand theft and espionage, only for Jonathan Kaye from the State Department to show up and tell McGarrett he's here to take custody of Wo Fat, drop all the charges, and take him to the airport for a flight back to Hong Kong. A livid McGarrett asks why, and Kaye says the feds are using Wo Fat for a PrisonerExchange with the Chinese to get back a U-2 pilot who was shot down in China 3 years earlier and held ever since.]]

BigNo: [[spoiler: Toni]] lets out quite a big one in "Thanks The Honeymoon" when [[spoiler: she discovers a mobster's attempt to kill her and new husband so she can't testify against him only ''partially'' successful.]]

* GettingCrapPastTheRadar: In "Tricks Are Not Treats", the writers apparently weren't allowed to refer to the pimps as pimps, but managed to work in Lolo's nickname for them: "pimples".

** In "The TheSign Of the Ram," literally has Jessica Humboldt standing in "Horoscope for Murder"'s Agnes Du Bois ([[ItMakesJustAsMuchSenseInContext They've traded practices, so she's in Albuquerque]]).

* TakingYouWithMe: [[spoiler:"Death with Father."]]

** In "The Sign Of Ram," literally has Jessica Humboldt standing in "Horoscope for Murder"'s Agnes Du Bois ([[ItMakesJustAsMuchSenseInContext They've traded practices, so she's in Albuquerque]]).

* WellDoneSonGuy: Elliot Bancroft in "Use a Gun, Go to Hell" ''really'' wants his dad to proud of him. [[spoiler: Shooting and killing a senator in favour of strict gun control[[note]]which his dad is very ''isn't''[[/note]], and throwing the gun away probably wasn't the best way to do it - since it leads to all the trouble in the episode.]]

* CriticalResearchFailure: Reverend Andy in "The Miracle Man" is from UsefulNotes/{{Manchester}} where he was discovered and he's said to have been in prison [[BlatantLies where he found God]]. Danny rings Wormwood Scrubs where he was indeed detained at Her Majesty's pleasure... but this attempt to avert BritainIsOnlyLondon would be more successful if Five-O had called Strangeways - a prison actually located in Manchester[[note]]Wormwood Scrubs is in ''London''.[[/note]]

* ChuckCunninghamSyndrome: Kono and Danno. [[spoiler: [[KilledOffForReal Sadly averted]] with Chin Ho.]]
