History Series / HawaiiFive0

* In a B-plot of one of the Halloween episodes, Danny Williams finds his house TP’d and wanting to find the perpetrator. Near the end he looks under his bathroom sink cabinet to find all the toilet paper gone, leading to the revelation that his daughter Grace was one who TP’d their house due to peer pressure from her friends. She does however state that she chose his house because she didn’t want to vandalize another person’s home.

%% ConspicuousCG: Animation trope, doesn't apply to a live-action series.

** Daniel Dae Kim and Grace Park are not scheduled to appear in the 8th season due to failed negotiations over being paid less than Scott Caan and Alex O'Loughlin. The production team said that due to this, the season will explain what they are doing when it airs in 2017.

* ArtisticLicenseGunSafety: To get the police out of the vehicle carrying the arrested robbers so they can get Catherine released in the fourth-season premiere "Aloha kekahi i kekahi", Steve [[FiringInTheAirALot fires into the air twice]], something a Navy SEAL should surely know is dangerous and reckless regardless of the situation.

** Lauren German as Lori Weston in the early episodes of season 2. Eventually she was [[PromotionToOpeningTitles promoted to the opening credits]]... sort of.

** Lauren German was sandwiched in between this and FakeGuestStar for most of her run as a series regular, shown as "Also Starring" in the first scene-post credits, before the actual guest stars were listed.

* VariationsOnAThemeSong: The 200th episode ""Pua A'e La Ka Uwahi O Ka Moe" has Steve looking into a case his grandfather worked in 1941. The show does a dream sequence set then with the opening theme having a '40s "big band" vibe to it.

** The [[http://www.youtube.com/watch?v=T7Ba_jz22sI opening titles]] are clearly an homage to [[http://www.youtube.com/watch?v=AepyGm9Me6w the 1968 original]]. This even includes the zoom in from the sky on each version's [=McGarrett=] at the beginning. No points for [[http://www.youtube.com/watch?v=FdZNQkF0sE4 using a sped-up homage of the first season ending credits with the police bike blue light]].

According to CBS, the 8th season could potentially be its last season. In addition, Grace Park and Daniel Dae Kim have departed from the show due to difference over their salary for being involved in the show.

* OpenSaysMe: Hey, suspect, when Five-O comes knocking, better answer unless you want this.

* CaliforniaDoubling: Well, Hawaii Doubling -- with the exception of the aerial footage over Osaka, the scenes in "Ua Hapa" where Steve looks for Wo Fat in Japan were actually filmed in downtown Honolulu. You could even see the Top of Waikiki through Wo Fat's hotel window.
** Averted in Season 4 when Kono was searching for Adam, eventually finding him in Vancouver. Grace Park had small parts in (or outright missed) several episodes due to her maternity leave, but filmed a few scenes in her hometown of Vancouver before returning to Hawaii to resume her role full-time.

* [[ChekhovsGun Chekhov's...]]
** ...Annoying Granny: The talkative granny that saw [[spoiler:Kono and Steve's break-in to the HPD evidence locker]] in "Hana'a'a Makehewa" shows up as [[spoiler:the one picking Kono out of a lineup]] in the Season 1 finale, "Oia'i'o."
** ...Cell Phone: In "Lanakila", Mary photographs all contents of the Champ box. In "Ke Kinohi", the bad guys have stolen the actual contents, so Five-0 relies on her pictures to continue the investigation.
** ...[[ChekhovsGunman Gunman]]: Wo Fat, the BigBad, is first seen as a golfing partner of the villain they're investigating midway through the first season.
** ...Gunshot Wound: In "Ho'opa'i", two agents on an FBI security detail are shot during a mob raid on an undercover agent's safehouse. One agent survives, but the other dies. Why? [[spoiler:Because the ammunition used to shoot the survivor only contains half as much gunpowder as a normal round would have, making the wound it causes much more survivable. This reveals that the survivor is the mob's mole.]]
** ...Newspaper: In "Powa Maka Moana", a woman survives pirate attack in which all of her friends get taken hostage. Her dramatic reunion with her lover is photographed and appears on the front page of the newspaper. [[spoiler: For her safety, Five-0 keeps her name secret. When the kidnapper calls Five-0, he demands that she deliver the money, but slips into calling her by her first name. It is later revealed that the woman and her lover are the bad guys.]]
** ...Inventory Control Documentation File: In "Ua Hiki Mai Kapalena Pau," it is revealed that the list of [[spoiler: serial numbers for the $28 million in the HPD evidence locker]], which everyone had thought was missing, was still intact. This allowed Chairman Akahoshi to determine that [[spoiler: the $200,000]] that Chin Ho "returned" actually [[spoiler: wasn't the same money that went missing]]. However, that same list will also establish that [[spoiler: $10 million of the $28 million]] isn't the same [[spoiler: $10 million]] that was originally there -- thereby exposing Five-0's [[DespairEventHorizon unauthorized]] [[spoiler:"borrowing" to ransom Chin Ho]] in "Hana'a'a Makehewa".
** ...Knife: In "Malama Ka Po'e", Grover makes good use of the pocket knife his son gave him earlier.

* BrokenAesop: Season 3's "Hookman," where Danny hits an [[StrawmanPolitical absurdly-stereotypical]] gun shop owner with an {{Anvilicious}} anti-gun lecture. According to him, ''his'' gun is a necessary tool, but regular citizens have no business having them. For a professional investigator, Danno doesn't seem to pay attention very well, as ''every single episode of the show'' features a violent crime happening to somebody (usually an innocent victim) with no means of defending themselves and the police nowhere in sight. The cops, including [[BadassCrew Five-O,]] [[TruthInTelevision show up some time later to document the scene, pick up the bodies, and (hopefully) catch the bad guys down the road]]. Factor in his own bullet-riddled RoaringRampageOfRevenge for the kidnapping of his daughter and later again for the murder of his brother, and you have a world-class {{Hypocrite}}.
** It would seem that real police officers don't subscribe to Danno's views on the matter, as demonstrated by [[http://www.policeone.com/police-products/firearms/articles/6188462-PoliceOnes-2013-Gun-Policy-Law-Enforcement-Survey-Results-Executive-Summary/ this survey]] that ''Police One'', a professional publication by and for law enforcement officers, conducted of its readership. Given that and other similar polls and studies...WriterOnBoard, anyone?

* GunsDoNotWorkThatWay: Usually averted pretty well, but "Hookman", the episode written by and guest-starring Peter Weller, goes completely off the rails. Weller's ex-sniper-turned-bank-robber lost his hands and now wears prosthetics, and is seeking revenge against the cops who crippled him. In the process, Mr. Weller demonstrates that, despite his oft-underrated acting talents, he doesn't know a damn thing about firearms.
** Like much of Hollywood, he doesn't know the difference between a clip and a magazine, something that gets unforgettably hammered into every military recruit during basic training. His character is supposed to be a retired Army sniper.

** The gun shop visited by Steve and Danny prominently displays lots of weapons that are banned in Hawaii, which has the most restrictive gun control laws of all 50 states. Danny takes the opportunity to deliver a tirade against the individual right to bear arms. While the episode tries to appear balanced with Steve peripherally offering a very halfhearted counterpoint, but the gun shop owner is such a [[StrawmanPolitical blatantly-exaggerated stereotype]] that it's a clear case of WriterOnBoard. Danny's speech about why people shouldn't be allowed to have guns, even for self-defense, [[BrokenAesop doesn't hold up very well]] in a show that features innocent people being murdered or kidnapped by violent criminals with the police nowhere in sight in ''every single episode''.
** Weller's character engraves the name of the intended target on each of his cartridges because, you know, ''[[RuleOfCool he's serious]]''. Except that anybody should see how that's a bad idea, considering that the cartridge case contains a small explosive charge (gunpowder) which, you know, ''explodes'' in order to launch the bullet. So grinding a bunch of weak spots in the side of the case is... perhaps not something an alleged highly-trained professional would ''ever'' do. The resulting case rupture would have some kind of bad result, ranging from (at best) jamming the weapon so badly that you need to field-strip it in order to clear the stoppage (and need a gunsmith to make sure it's safe to fire again), to the receiver literally blowing up in your face (shooters poetically refer to this event as a ''kaboom'').

** Deep-sea diver Blake Spencer's grandmother, suffering from Alzheimer's disease, in the season 2 episode "Mea Makamae" is played by Patty Duke (of ''Series/ThePattyDukeShow'' or ''Theatre/TheMiracleWorker''), who guest-starred in the original series' season 5 episode "Thanks for the Honeymoon" in 1973.

* AntiClimax: The winter finale of Season 7 ends on a very intense and gripping cliffhanger, but come the first episode into the new year, the cliffhanger is resolved ''less than five minutes into the the next episode''. Not only that, but the following episode delves into a one-off story completely detached from the previous one. Basically, all it amounts to is the previous episode ran long and the excess got tacked onto the beginning of the next one, and in doing so, the ending wasn't SpoiledByTheFormat. The winter finale could've aired as a slightly over-length special, but then it would be difficult to rerun it without chopping it down to fit a general-purpose sixty-minute time slot.
