If kids can build anything with LEGO Bricks, just imagine where Adult Fans of LEGO can take things...
  • Alternative Character Interpretation: Is the Santa's Workshop set the real thing or a kitschy mall setup for children to visit with their parents?
  • Archive Panic; Lego has been around since 1932 and has produced an innumerable amount of brick sets since 1949 and is showing no signs of stopping. If you want to be a Lego collector, be certain that you have cash to burn.
  • Broken Base: Believe it or not, the beloved minifigures. There are plenty of fans who feel that they detract from the built models and are only used to sell sets. They're not completely off, though.
  • Crack Is Cheaper: As mentioned in the Main article, prices are on the rise, especially in the licensed themes.
  • Fandom Berserk Button: They are not called "LEGOs", the pieces are called "LEGO bricks" and the toys themselves "LEGO sets."
  • Fandom Rivalry: There is a well-established three-way Friendly Rivalry among fans of the three eldest LEGO Themes: LEGO Space, LEGO Castle, and LEGO Trains.
    • LEGO Vs Mega Bloks shorts on YouTube are not uncommon. Both are similar in design and use, and LEGO did sue Mega Bloks in the past.
  • Memetic Mutation: "I hope you step on a LEGO brick, barefoot, in the dark."
  • Misaimed Marketing: Cleverly averted. The 2016 DC Super Heroes set managed to tie in loosely to Suicide Squad (2016), but avoided any outcry over the subject material by using the comic versions of the Squad instead.
  • Moe: The cute minifigures (especially the original ones with the simple dots for eyes and a curve for a smile that predates the character art designs of Adventure Time) tends to fall into this.
  • Moment of Awesome: See here.
  • Money, Dear Boy: Most say it's popular only because the company wouldn't stop "blowing up". It quickly became a major corporation, and has been gradually getting bigger and bigger, branching out into other avenues of entertainment (series with franchises of their own, movies, commercials, video games, board games, theme parks, etc.) to the point where the creators forget that you are just supposed to build actual plastic bricks with them! Of course, the haters often ignore how the company had eight decades to prepare for this. The book Brick by Brick by David Robertson provides an accessible insight into this phenomenon, pointing out that the company's branching out around the Turn of the Millennium actually decreased their profits, and it was only due to their in-house products like BIONICLE and the then-released redesigns of classic older sets that they managed to avoid bankruptcy. So while the complaint is partially true, LEGO has already learned the hard way how to keep their standard building toys and other departments balanced without relying too much on either.
  • Nightmare Fuel: 4000031 A LEGO Christmas Tale is a charming Christmas-themed set featuring Santa Claus on his sleigh, elves making toys, children opening presents, and a snowman with a skull for a head.
  • Older Than They Think/They Changed It, Now It Sucks: Specialized pieces and sets devoted to building one specific model have been around since 1955. Despite this, for many years now there has been a seemingly inexhaustible supply of people in their 20s or 30s lamenting this "recent" development and fondly recalling how it was all just boxes of random generic bricks when they were kids.
  • Periphery Demographic: LEGO is primarily a toy for children. It is immeasurably popular with teenagers and adults.
  • The Scrappy:
    • Several parts and themes over the years. Galidor is a noted example.
    • Stickers. Most fans hate these because they don't last, can be difficult to align, and seem lazy. Never mind that printing every single part that required decoration is costly and would raise the price of sets. Of course a set with liberal sticker use (or several designed to match up) like the Mystery Machine, will be lamented.
    • Rubberbands (for sets like the Bohrok and the many, many X-Wing sets) suffer a similar fate, but unlike stickers, they're fairly easy to replace.
    • Studs. Their inherently tiny size makes them hard to keep a grip on and very, very easy to misplace.
  • Scrappy Mechanic:
    • LEGO sets with brightly-colored Technic pins or liftarms for mechanisms. Even when the pieces are color-locked, they're not always covered up properly, which can annoy adult builders.
    • Stickers, as stated above, especially when they're clear-backed, which means a risk of air bubbles or smudging underneath them.
  • Ugly Cute: Attempts to make more intimidating or monstrous-looking characters with the normally adorable minifigures, like the Orcs from the Lord of the Rings sets, tend to have this effect.
  • Unfortunate Implications:
    • Part of the fun in LEGO is that it's supposed to be, determinedly, a toy for both boys and girls. So naturally, many of the LEGO lines aimed directly toward young girls would tend to have these. Many have placed focus on domestic "feminine" activities, such as a resort set with focus on leisure activities, as well as a LEGO jewelry-making set. The LEGO Friends, the most recent attempt at marketing toward girls, has had some of the most criticism. Unlike the jewelry-making set, it directly advertised its affiliation with LEGO bricks, but the toy figures were modeled more after the idealized feminine image similar to fashion dolls (while the resort LEGO sets still kept the blocky-looking figures). This LEGO CUUSOO project attempts to offset the problem.
    • And even that CUUSOO (or should we say now, LEGO Ideas) project came with its own slew of Unfortunate Implications, along with the headline-making female scientist figure from LEGO Minifigures. Just try to find an Internet discussion regarding either the Ideas project or the female Scientist that doesn't have an argument started by someone saying, "What's the big deal? If these were male characters, this wouldn't be newsworthy."note  For example, here is a discussion resulting from LEGO selecting a second Ideas project revolving around female scientists.
