->''"Franchise/{{Godzilla}} is either breaking the laws of physics or he's throwing around an empty rubber suit!"''
-->-- '''Tom Servo''', ''Series/MysteryScienceTheater3000''

When {{special effects}} look really cheap and dodgy, to the point of pulling the audience out of the narrative, you have a Special Effect Failure. All-too-common prior to 1980, and still with us today despite relatively inexpensive digital effects that can be very convincing and realistic... but often [[ConspicuousCG aren't]].

The audience's expectations for effects have grown up with the media. For example, it is obviously a dummy being thrown from a train in ''Film/TheGreatTrainRobbery'' -- but since it was filmed when filmmaking ''itself'' was in its infancy (1903 to be exact), people forgave it. If a modern remake had done that, however, they would not have been nearly as kind. It should also be noted that with the modern push to update everything to HD can also result in a retroactive form of this, as a matte painting in a 1980's VHS release looks fine, but on the cleaned up, [[DigitalDestruction "remastered"]] Blu-ray looks like, well, a cheap matte painting in the background.

Sometimes a Special Effect Failure is caused by resorting to OffTheShelfFX. Many examples are just plain {{Blooper}}s (a literal failure of the effects). In a video game it can be because of ModelDissonance being revealed by a glitch or oversight.

Sometimes cheesy FX are regarded as part of the SoBadItsGood charm of a work. Sometimes authors will [[IntendedAudienceReaction intentionally aim for this]] as a form of StylisticSuck.

* The Chinese animated series ''The Adventures of Kiki and Qeqe'' have several animation errors; for example, one of the titular characters in the air appears frozen.

[[folder:Fan Fic]]
* InUniverse from ''Fanfic/CalvinAndHobbesTheSeries'', combined with NightmareRetardant:
--> '''Hobbes:''' Bumper cars are fine when there aren't ghosts constantly flying down in your face!\\
'''Calvin:''' They were ''paper'' and on ''fishing line!''
* The “destruction” of Munich terrorist facility in ''Franchise/JamesBond'' fan film ''WebVideo/DiamondsCut'' seems to intentionally go for the Camp factor with what seems like a really bad photoshop. Absolutely nothing collapses and the only signs of destruction are little tongues of flame with thin tendrils of smoke at the forefront.
* Essentially all of the special effects in the animated version of ''FanFic/TheEndOfEnds'', but [[spoiler:Count Logan's dragon form breathing fire]] stands out.
* In ParodyFic ''Plan 7 of 9 from Outer Space'', the alien abductor D'Ork of the Thorkoth looks like a cheap prop from a Creator/RogerCorman [[Film/ItConqueredTheWorld film]], has a KillerRobot that's just a [[Film/RobotMonster diving helmet on a gorilla suit]], and pilots a FlyingSaucer that's held up by visible strings.

[[folder:Literature]]
* In-universe example in ''Literature/DiaryOfAWimpyKidDoubleDown'', where middle school student Greg Heffley tries to create a homemade horror movie on NoBudget:
** Rowley is the only actor, and has to [[ActingForTwo act for many]]. Since Greg has no video editing skills, this means that no scene in the movie can feature more than one character.
** Rowley [[CrosscastRole plays an unnnamed woman]]. Unfortunately, he refuses to wear a dress, and they don't have a wig for him. He ends up wearing yoga pants and a hooded sweater, and having the character never show her face.
--> '''Woman''': I hope you don't mind if I don't turn around but I am really concentrating on doing these dishes.
** They try to make a scene in which an unnamed man tries to take a shower, but worms come out instead of water. Greg can't find a way to make it looks natural, and settles for throwing gummy worms at Rowley's face and hoping it'll look realistic once they make the final cut.
** They use ketchup as fake blood.
** Discussed when Greg points out that he still hasn't figured out how to film the climax of the movie, which would feature a battle against a giant worm. Sadly, they never get around to attempting this scene at all.

* Digitally-overlaid graphics can often go awry;
** One time, ESPN's 1st down line during a football game [[https://twitter.com/WillBrinson/status/916803189617328128/photo/1 rendered on an angle]].
** During game 2 of the 2017 World Series, a Masterpass sign was digitally added to the outfield wall with a chroma key, but at one point, it accidentally overlaid on top of a player's head.

[[folder:TV News]]
* Quite a few examples exist of two main failures: putting up the wrong headline or accompanying image (the small pics appearing next to a news anchor's head for each story) and someone who decided to wear the wrong shade of blue or green, causing the clothing to pick up images or video meant for the green/blue screen behind the anchor. Weather forecasters are particularly prone to the second one, given all the use of this type of imaging in their segments.
* People responsible for news graphics are only human, and sometimes they put up a picture of the wrong person. [[https://www.youtube.com/watch?v=lnCnRuoYMxE Here is a case where that happened.]]
[[/folder]]

[[folder:Webcomics]]
* Pretty much the whole of the ''WesternAnimation/AvatarTheLastAirbender'' fancomic ''[[Webcomic/HowIBecameYours How I Became Yours]]''. Special mention goes to all the copied poses. Diaz copies from everything, mostly the show itself (though she often uses [[Manga/{{Bleach}} Ichigo]] as a model for Zuko), and often uses the same artwork over and over (Iroh is depicted in the "holding out the white lotus tile" pose from "[[Recap/AvatarTheLastAirbenderTheWaterbendingScroll The Waterbending Scroll]]" several different times). He's also depicted in a pose from "[[Recap/AvatarTheLastAirbenderTheStorm The Storm]]" wherein he is in a dark room and lit from below by a fire, and no attempt was made to change the lighting, despite the ''How I Became Yours'' scene taking place in bright sunlight.
** She also has a nasty habit of making characters change position by rotating their models, which tends to make them look more like mannequins than people. The most infamous example is when Sokka and Zuko carry Aang off after a sparring session, but it also makes the Toph/Aang sex scene unintentionally hilarious when you realize that the characters are in the ''same position'' the entire time.
** When Diaz ''doesn't'' copy, the characters tend to look UncannyValley, like one scene where Aang has a twelve year old's face, a teenager's body, and elongated limbs.
* Ever-omnipresent, as long with OffTheShelfFX, in ''Webcomic/TheBMovieComic''.
* In ''Webcomic/CommanderKitty'', [[http://www.commanderkitty.com/2009/12/06/mittens-has-a-cunning-plan/ Mittens and Fluffy's plan for creating a fake teleporter effect involves distracting Ace right before CK himself shows up with an accompanying spray of glitter.]] [[http://www.commanderkitty.com/2010/07/11/hot-sparkly-adventure/ The actual execution leaves much to be desired as well.]]
* Parodied by ''[[http://freefall.purrsia.com/ff500/fv00448.htm Freefall]]'', where cheesy special effects have been painstakingly re-created by CGI, including the wires.
* Referenced in ''Webcomic/SkinHorse'' where UNITY refers to Tip's new wolf form as a [[http://static.tvtropes.org/pmwiki/pub/images/sh090801ringed_by_cherry.jpg plywood shark.]]
