History YMMV / SixFlags

** Whizzer at Six Flags Great America, at first, was going to be replaced with Superman: Ultimate Flight. [[TheyChangedItNowItSucks The overwhelming outcries]] and its [[EnsembleDarkhorse popularity]] (due to being the only Anton Schwarzkopf Speedracer coaster in the United States) made the park change their minds at the last second, and instead replaced [[SeinfeldIsUnfunny Shock]][[TroubledProduction wave]].

* SeinfeldIsUnfunny:
** Revolution at Six Flags Magic Mountain is not only the oldest existing looping coaster, but also [[TropeCodifier the first constructed]] after many years of looping coasters not being built. It's difficult to appreciate this fact when the coasters surrounding it dwarf it in size, speed, and design, especially when the coaster with the world's ''largest'' vertical loop (Full Throttle) is only a short walk away. However, it's currently undergoing renovation to keep it up to date.

It still remains for its [[GrandfatherClause historic significance]] and appeal to families with smaller children.
---> "In 1966, the summer debut of the Runaway Mine Train was an overwhelming success. By today’s standards, the height and speed appear pretty tame, but for the 1960s, it was state of the art."

* SugarWiki/AwesomeMusic: Aside from Mr. Six's theme ("We Like to Party" by Vengaboys), when Premier took over ownership in 1999 (and began converting their parks to the Six Flags name while adding stuff to others), they included a majestic new theme in their commercials (warning: the flashing screens in these ads may cause seizures).

** Six Flags Magic Mountain has sometimes been given the nickname “Wally World” by fans due to its inclusion in a certain film. See HeyItsThatPlace below.

* DevelopmentHell: Southwest Territory at Six Flags Great America had been planned as early as 1979, during Marriott's ownership of both it and California's Great America. It didn't come to exist until 1996.

* TheScrappy:
** Green Lantern: First Flight at Six Flags Magic Mountain has gone down as one of the worst amusement park rides ever built. This is a result of the ride movements being incredibly shaky to the point of being outright painful. This was especially bad for male riders, who complained of the pain to their [[GroinAttack "region,"]] upon riding. Thankfully, the ride was closed in 2017. It was set to be sent to La Ronde in 2020 (renamed Vipère), but the project was cancelled in 2022.
** In the way of parks, Six Flags America and La Ronde are often touted as the two worst, though for directly opposite reasons. Six Flags America is criticized for having decent rides, but terrible park maintenance, while La Ronde is criticized for decent park maintenance, but terrible rides.

* SugarWiki/DevelopmentHeaven: Six Flags went on a spending spree from 1999 to 2001, installing 21 coasters each year in 1999 and 2000 before constructing ''X'' in 2001. This business model was too good to be true - the chain eventually went bankrupt in 2009.

** Some purists consider Six Flags' decision to RMC the Texas Giant and Colossus as this.

* RescuedFromTheScrappyHeap: In recent years, several old and/or unbearably rough wooden coasters throughout the Six Flags chain [[note]]Texas Giant at Six Flags Over Texas, Rattler at Six Flags Fiesta Texas, Medusa at Six Flags Mexico, Colossus at Six Flags Magic Mountain, Cyclone at Six Flags New England, and Georgia Cyclone at Six Flags Over Georgia[[/note]] have gotten converted by Rocky Mountain Construction into hybrid coasters, making them much smoother. Not only that, but they also got redesigned layouts that have modern steel coaster elements such as taller and steeper drops, overbanked turns, and even ''inversions'', while still keeping true to their original designs. Needless to say, these coasters are much more popular as hybrid coasters than they were as wooden coasters. Though some old school Magic Mountain fans [[TheyChangedItNowItSucks weren't too happy]] when Colossus, widely considered to be a pop culture icon due to its appearances in many movies and TV shows, was given this treatment...

** Fans of ''WesternAnimation/ThomasAndFriends'' felt this way after the ''Thomas Town'' lands in their parks were rethemed to ''Whistlestop Park''. Didn't help that a lot of the trains in that area still have paint jobs that make it clear they were supposed to be characters from the show.

* BrokenBase: ''Viper'' and Riddler's Revenge'' at Six Flags Magic Mountain. Some consider them to be intense rides with large, unique layouts, while others find them too rough to enjoy.

This is a result of the ride movements being incredibly shaky to the point of being outright painful. This was especially bad for male riders, who complained of the pain to their [[GroinAttack "region,"]] upon riding.

* JustHereForGodzilla: Many people come to Six Flags Great Adventure so let to ride Kingda Ka, the world’s tallest roller coaster.

* TheScrappy: Park-wise as a whole, La Ronde. International guests attending there often complain that the workers, mainly the ride operators (who speak French), are outright rude to any English-speaking guests.

* SavedByTheFans: Whizzer at Six Flags Great America, at first, was going to be replaced with Superman: Ultimate Flight. [[TheyChangedItNowItSucks The overwhelming outcries]] and its [[EnsembleDarkhorse popularity]] (due to being the only Anton Schwarzkopf Speedracer coaster in the United States) made the park change their minds at the last second, and instead replaced [[SeinfeldIsUnfunny Shock]][[TroubledProduction wave]].

** Inverted with the replacement of Magic Mountain's Psyclone with Apocalypse. Because of how unbearably rough Psyclone was (even by wooden coaster standards)[[note]]the ride's foundation was damaged from the 1994 Northridge earthquake and permanently affected the coaster[[/note]], replacing it with the smoother Apocalypse was ''necessary''.

* MostAnnoyingSound: The loud, jet-like, migraine-inducing sound produced by some launched coasters like Superman: Escape from Krypton at Magic Mountain and Vertical Velocity at Great America and Discovery Kingdom. Especially bad, if you're standing right under or next to it.
