Editing Reset button technique (section)

==One-off use==

The effective use of this device in productions where it is not typically featured relies heavily on the audience's [[suspension of disbelief]] until the precise moment when the reset button technique is employed. {{Citation needed|date=June 2024}}The successful execution of this technique needs the introduction of plot developments that significantly alter the course of the show, without indicating that continuity will be disrupted. Often employed as a [[plot twist]], the reset button technique serves to undo all the preceding events of an episode. This device draws inspiration from science fiction and metaphysical concepts and is frequently included in those genres.

Examples of the [[Reset (computing)|reset button]] technique include [[dream sequence]]s, alternate-history [[Flashback (psychology)|flashbacks]], [[Parallel universes in fiction|parallel universes]], alternate realities, alternate timelines, [[Daydreaming|daydreams]], [[time travel]], and [[hallucination]]s. In one trope that uses this technique (typically in science fiction or fantasy), a character will find themselves in a situation that seems familiar, but during the episode, some things seem odd. Then one or more major events happen, such as the death of a lead character. By the end of the episode or [[story arc]], the character realizes that they have been placed in a copy of their normal surroundings, usually to try to obtain information from them, and that the mastermind behind the plan made a few mistakes in fashioning the copied environment.

One popular example<ref>{{Citation |last=Katzman |first=Leonard |title=Return to Camelot: Part 1 |date=1986-09-26 |url=https://www.imdb.com/title/tt0818199/ |series=Dallas |access-date=2022-08-17}}</ref> of the reset button technique is the [[1986 in American television|1986]] [[season premiere]] of ''[[Dallas (TV series)|Dallas]]'' in which it is revealed that [[Bobby Ewing]]'s death in the previous season was merely a [[dream]] in the mind of one of the characters. This was parodied in the "[[Da Boom]]" episode of ''[[Family Guy]]''. In [[comics]], the [[Spider-Man]] storyline ''[[Spider-Man: One More Day]]'' undid the marriage of Peter Parker and [[Mary Jane Watson]], drawing criticism due to the continuity issues, {{who|date=May 2016}} with some critics even comparing it to ''Dallas''.

However, when used appropriately, it can be devastating in terms of its effect. Near the end of the series finale of ''[[Newhart]]'', innkeeper Dick Loudon (portrayed by [[Bob Newhart]]) is struck on the head and knocked unconscious. The scene switches abruptly to Dr. Bob Hartley, the character Newhart portrayed in his earlier series, ''[[The Bob Newhart Show]]'', waking up in bed next to his wife Emily (portrayed by [[Suzanne Pleshette]]). Hartley describes the strange dream he has just had about running a Vermont inn, which Emily blames on the Japanese food he ate before going to bed. The entirety of ''Newhart'' is thus established to be part of Hartley's dream.
