** Some of the cases featured on the show might have been solved nowadays with recent advances in technology. Take the nightmarish case of [[http://unsolvedmysteries.wikia.com/wiki/Bill_and_Dorothy_Wacker Bill and Dorothy Wacker]]. They were harassed and stalked for years by an unknown assailant or assailants. Had this happened today in the 21st century, things may have been different. For example, caller ID is a standard feature on phones and may have made it easier to identify their stalker. Also, digital camera technology has made said devices cheaper and smaller; hidden cameras might have ended up catching the face of their stalker.

* UnintentionalPeriodPiece: The heavily synthesized music and the graphics used in the various introductions are hopelessly stuck in the 80's/early 90's, but arguably not to the show's [[CrowningMusicOfAwesome detriment]]. The fashions and attitudes in the cases themselves are also obviously of their time, especially the younger women with "80s hair".

* CriticalResearchFailure: The sister of Tami Lynn Leppert (who went missing in the 80s) once criticized the UM segment featuring her as they got many facts about her disappearance wrong, from the clothes she was wearing, to the car she was last seen getting into. Her sister also pointed out that Tami was ''pregnant'' at the time of her disappearance, but the re-enactment doesn't mention that. Predictably, when the case was shown again years later during the Dennis Farina era, none of the above mistakes were corrected (the era was fond of reusing the same segments from the original series untouched aside from flashy new effects and transitions).
** Less-than-savory aspects of the lives of some of the murder/missing person stories are also left out, despite the possibility that they could provide information as to is responsible for their death/disappearance.
** The "Billy the Kid" segment omits the facts that Brushy Bill's own family denied that he was Billy the Kid, and that then-recent computer analyses of photographs of both men called Brushy Bill's claim into question. Additionally, the show regarded Brushy Bill's claimed age (in 1950) of 91 years as an undisputed fact, when his own family maintained that he had been born in 1879, making him 71 at the time of his death (and only two years old when the 21-year-old Billy the Kid was killed).

* RetroactiveRecognition: Creator/MatthewMcConaughey, Creator/DanielDaeKim, Creator/CherylHines, Creator/JamiesonPrice, Creator/DougJones, and Creator/Stephanie Weir in addition to Taran, mentioned above,all made early appearances on the show.

** The granddaughter of [[http://unsolvedmysteries.wikia.com/wiki/Terri_McClure Terri McClure]] was also not happy with the show's investigation into her grandmother's murder. Terri's prime murder suspect has always been her own son Timothy, although he was never convicted, supposedly due to lack of hard evidence. Terri's granddaughter criticized the show's producers for interviewing only ''Timothy'', '''the prime suspect''', but not any other family members, as many of the statements Timothy gave were not true, or [[BlatantLies outright lies]] (such as when exactly he called to have his mother's credit cards canceled). She also states on the Unsolved.com site that much of the remaining family members believe, without a doubt that Timothy murdered his mother, ''but the show's narration by Robert Stack and Dennis Ferina'' claims they ''do not'' think he is guilty, and defend him all the way!
