History YMMV / LEGO

** There are no sets based on the Film/XMenFilmSeries for similar reasons despite popular request, and the only two X-Men sets released were based on Marvel's comics. Part of this can be blamed on the fact that Marvel's heads at the time were trying to screw them and The Fantastic Four[[note]]who haven't gotten any sets in LEGO either, with only Dr. Doom coming out in a single Spider-Man set in 2013[[/note]]out of any publicity to spite 20th Century Fox for having the film rights, but even when Disney bought FOX, it took until ''2022'' for Marvel's merry band of mutants to come back to LEGO, and even then for a single set thus far.

** The lack of a proper ''Shazam!'' theme was quite a bummer, considering how ''Film/Shazam2019'' came out around that time and all previous DCEU movies got a proper set. Granted, there was a figure of Shazam in the new ''Batman'' theme and LEGO likely refused the idea due to trying to avert SpoiledByTheMerchandise this time, there is quite a lot that could've been done with characters from the movie who only appeared in the trailers so far.

* JustHereForGodzilla: Some otherwise average sets regularly fetch for high prices in the resale market due to the desirable minifigures they contain. For instance [[https://brickset.com/sets/75012-1/BARC-Speeder-with-Sidecar 75012 BARC Speeder with Sidecar]], a small ''Franchise/StarWars'' set that builds two simple speeder bikes, retailed for $25 but can fetch 10x the price nowadays due to it containing a unique, detailed minifigure of [[WesternAnimation/StarWarsTheCloneWars Captain Rex]].

** Identical minifigures that show up in almost every set in a theme are generally disliked, especially those that have no story related reasons to be included. For instance, Owen Grady shows up in three of the four ''WesternAnimation/JurassicWorldCampCretaceous'' sets, despite not being a character in the series. This issue is mostly played straight for figures which aren't faceless Mooks (so this say, doesn't apply to cases like Robo SWATs or clone troopers.).
** ''Franchise/StarWars'' fans have several [[https://brickset.com/article/33731/what-is-the-worst-lego-star-wars-set universally disliked sets]], whether due to poor build quality, inaccuracy or downgrades, poor minifigure selection, or bad pricing. This includes 75098 Assault on Hoth (due to being a mish-mash of smaller play sets and not living up to the Ultimate Collector's Series name), 75199 General Grevious's Combat Speeder (a comically out-of-proportion and heavily overpriced set) and 75201 First Order AT-ST (an incomplete model that costs the same as the previous released complete one).
** Many ''Star Wars'' fans also tend to heavily dislike "gimmick" battle packs, which are battle packs that feature lesser known, deep cut, and absurd forces as the feature, [[labelnote:Examples]] 75198 ''Tatooine Battle Pack'',75167 ''Bounty Hunters Speeder Bike Battle Pack'', and 75088 ''Senate Commandos Battle Pack''.[[/labelnote]] primarily because these are the battle packs where one can heavily agree that they take away the primary appela of these battle packs (to build an army).
** ''Star Wars'' fans also tend to dislike the minifigures in the initial ''[[WesternAnimation/StarWarsTheCloneWars Clone Wars]]'' sets from 2008-14, due to their [[https://blocksmag.com/why-did-lego-star-wars-the-clone-wars-minifigures-have-weird-eyes/ large cartoonish eyes]], which were designed to imitate their appearance in the series, but many felt that they end up [[NonStandardCharacterDesign clashing with the aesthetics]] of regular Lego minifigures. This was dropped when sets based on ''WesternAnimation/StarWarsRebels'' came around, with some hate of the series's cartoony portions carrying over to here (primarily in regards to the stormtrooper helmets.

** On March 10th, 2020, LEGO [[https://twitter.com/NintendoAmerica/status/1237363045271126017 announced]] a partnership with Creator/{{Nintendo}} to create sets based on ''Franchise/SuperMarioBros'' This was surprising due to how Mario was associated with LEGO's rival K'NEX (though it's most likely their license expired) and the fact that Mario's formal rival ''Franchise/SonicTheHedgehog'' has appeared in ''VideoGame/LegoDimensions'' but has yet to receive a proper LEGO set outside of Ideas.

** Shooters. Stud shooters, flick missiles, or large cannons are generally disliked by older collectors as they tend to stick out and look odd. Fans of series such as Ninjago or Star Wars have also grown tired of them due to being included in practically almost every set. LEGO Star Wars collectors also dislike how they've been replacing plenty of unique and diverse molds of blasters in favor of uniform stud shooter guns. As play features, they also serve no purpose to collectors who like to display their sets and keep them in tact rather than playing with them.

** Even if you just want to be a LEGO builder, buying bricks at all will cost you quite a bit; good luck tracking down bricks for more obscure colors for cheap, as quite a few bricks were, of course, only released along with specific sets that collectors already have to pay a lot of money to find--sending you down the Archives anyhow. [[TakeAThirdOption You could just buy the bricks secondhand]], [[CrackIsCheaper but]]...

** LEGO Vs Mega Bloks shorts on Website/YouTube are not uncommon. Both are similar in design and use, and LEGO did sue Mega Bloks in the past. LEGO fans tend to consider Mega Bloks just a ShoddyKnockoffProduct, while Mega Bloks fans consider LEGO [[CrackIsCheaper overpriced]]. It doesn't help that both companies have used some of the same licenses at different points (like ''WesternAnimation/SpongeBobSquarePants'', ''WesternAnimation/ThomasAndFriends'', and ''WesternAnimation/{{Minions}}''), which has inevitably led to comparisons between them and arguments over who did the license better.

* FandomRivalry: There is a well-established three-way FriendlyRivalry among fans of the three eldest Toys/LEGOThemes: Toys/LEGOSpace, Toys/LEGOCastle, and Toys/LEGOTrains.

* AnimationAgeGhetto: Despite LEGO marketing itself as an all-ages affair and having made sets specifically aimed toward adult collectors, LEGO is commonly regarded to be something only young kids can enjoy and something they are expected to "outgrow" past a certain age, with adult LEGO fans being seen as [[{{Manchild}} immature losers]] by some. It doesn't help that LEGO sets — including the adult sets — are frequently sold in the kids' toy aisle in stores and that most LEGO sets are based on [=IP=]s aimed at children (including some of [[MisaimedMarketing the adult sets]]), adding to this mindset.

This was dropped when sets based on ''WesternAnimation/StarWarsRebels'' came around.

* FandomHeresy: There are many Lego fans who consider it sacrilegious for minifigures to be colored anything other than yellow, outside of licensed themes. Some purists even detest modern yellow minifigures for [[TheyChangedItNowItSucks abandoning the original minimalistic dot eyes]].

*** [[Franchise/DuckTales The Duck triplets]]. Yes, they're the main characters of a popular cartoon, but adding them is a very risky move, since they take up three spaces. Not too mention that they [[SingleMindedTwins hardly count as seperate characters]], before [[DivergentCharacterEvolution their retooling]] in ''WesternAnimation/Ducktales2017'', at least.

* ValuesDissonance: It's very unlikely that [[https://brickset.com/sets/215-1/Red-Indians set 215 "Red Indians"]] (who are literally coloured red rather than the usual yellow), or even the 1990s Western sets, would be considered acceptable in the 2020s.

** The Big-figs are an even [[{{JustForPun}} bigger]] case. While some like them for the amounts of detail they provide, others dislike them because of having only two joints and two possible ways to customize them, the fact that they're [[JunkRare incredibly hard to get]], or simply because they prefer [[TakeAThirdOption the mini-fig/big-fig]] [[EnsembleDarkhorse combination variant]].[[note]]e.g. [[WesternAnimation/TeenageMutantNinjaTurtles2012 Leatherhead.]][[/note]] In 2023, LEGO added another movable part to big-figs: the head. Older ones didn't have a rotating head.

* ItsTheSameSoItSucks:
** Fans of ''VideoGame/{{Minecraft}}'' tend to complain about the relatively simplistic character designs of the minifigures, especially since the ''Minecraft'' artstyle is already simplistic to begin with. What really grinds their gears is that the Steve figure, despite LEGO being entirely capable of creating a high-quality version, still has no short sleeves or shoes, and his skin still being light instead of tan. The Zombies have the same problem, but they usually get a pass, since making highly detailed figures for {{Mook}} characters is not exactly plausible. The Alex figure also gets a pass, since her design is at least somewhat detailed in comparison.

** EpilepticTrees: There is a collection of people who believe that certain LEGO Creator sets are the designer's attempts to circumvent the ban on military technology that LEGO has set as a policy, by having the sets appear in civillain markings and changing just enough details to make it inconspicous, with the biggest pointer being set 31039, which according to some fans heavily resembles the F-35 Lightning II, and another one being set 4953, which fans have interpeted as an F-14 Tomcat.
