These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Adaptation Displacement: Depending on where you live. The comics that the show was based on seem to have grown rather obscure in America, but in most of Europe, the comics are still far better known than the cartoon. In France, the comics are still well known while most people hardly even heard of the cartoon.
Awesome Music: Pretty much the entire instrumental score, rich with leitmotifs and themes that uplift and inspire. Pay any attention to the music, particularly during the "Treasure of the Golden Suns" five-parter, and it becomes apparent how much love Ron Jones poured into scoring this series. It's a positive tragedy that, to this day, Disney Records still hasn't released the BGM to the public on a CD collection. It's perhaps an even more appalling tragedy that even among DuckTales fans, those who pay enough attention to the score to merit a CD release comprise a very small pocketfandom.
Base Breaker: Much like the second season as a whole, either you like Gizmoduck/Fenton, or you hate him.
Broken Base: Some fans feel that season two was inferior to the first and that it had weaker animation and missed the adventure stories that made up season one. Others felt that the second season was just as strong as the first.
Ensemble Darkhorse: Launchpad, who later went on to become Darkwing Duck's sidekick. Ironically, when Launchpad started appearing in non-''DuckTales'' related comics, he was poorly received by comic readers and accused of being an unnecessary carbon copy of Donald. Which is really weird, considering that Launchpad hardly ever gets angry or complains about doing what he's told to do. Donald's defining characteristic, on the other hand, is his temper.
It's really not that weird. Launchpad isn't similar to Donald personality-wise, but the role he played on DuckTales was an obvious stand-in for Donald's usual role in the comics. Since the comics already have the actual Donald, Launchpad is a rather pointless character in most of his comic appearances. This, coupled with writers not knowing what to do with the character, probably led to some readers thinking of Launchpad as, essentially, "Donald minus his personality".
Glittering Goldie, who appeared in a handful of episodes despite only appearing in one Carl Barks story. Rosa also padded out the character a lot in comics that mostly came after the show, including his epic masterpiece.
Gizmo Duck, plain and simple. He turned an accountant into the most powerful array of mechanical components and accessories who is a bodyguard and security guard for Scrooge, as well as a super hero to Duckburg and even went on to help Darkwing Duck protect St. Canard.
Evil Is Sexy: Magica De Spell, Circe, Cinnamon Teal, Feathers Galore and Boom-Boom Beagle.
Hilarious in Hindsight: In "All Ducks on Board" The Phantom Blot was boasting about how evil he is by saying "I am the Phantom Blot! I make Darth Vader look about as scary as a hood ornament of a 53 Buick! Compared to me, Dr. Doom is a wimp!" Guess what franchises Disney eventually got ownership of?
Memetic Badass: Scrooge seems pretty strong to be able to swim through a pile of gold coins.
Memetic Sex God: Magica De Spell, Circe, Cinnamon Teal, Feathers Galore and Boom-Boom Beagle.
Moral Event Horizon: The Beagle Boys mainly resort to burglary and thievery throughout the show, and don't really harm anyone. However, they cross this line BIG time in the series finale, when they turn Huey, Dewey, and Louie into golden statues, essentially killing them...though the effect is reversed at the end of the episode. They get their comeuppance when they suffer the same fate.
Fritter O'way in "Down and Out in Duckburg" was already a Jerk Ass, but once he discovers that Scrooge can get his fortune back, he goes to where he and the others are at and opens fire on them with a rifle intent on killing them or sinking their ship.
No Problem With Licensed Games: The Duck Tales NES game is very much in the running for being the best example of this trope; the game actually became a classic and is considered one of the finest games made during the 8-bit era, by Capcom or anyone. Its sequel is rare, but had similar reception. In modern times, it's ranked up along with Golden Eye 1997 and Kingdom Hearts (which is, interestingly, another Disney property) as an example of a licensed game done right.
Hell, Game Informer and EGM have BOTH placed it at #2 of all-time...
In fact, as it says on the game's page, the game is SO popular it's getting an HD remake.
Critical Dissonance: The remake's rather divisive; quite a few critics savaged it, but quite a few YouTubers loved it.
Disappointing Last Level: The last level of the game is... Transylvania. Which you had to go through twice before, and it's exactly the same as it was before. Subverted in the remake, where the last level is replaced by Mount Vesuvius, aka Magica's lair.
It's the Same, so It Sucks: A lot of critics threw this accusation at Remastered, saying that choosing to marry modern visuals and storytelling devices with 1989 gameplay was a stupid idea, and that Disney and WayForward should have made a completely new game from scratch.
Pandering to the Base: Remastered, possibly, with its references to the Moon level themenote which has become Memetic Mutation in both the level select theme, and the ending credits music (which is the TV theme song, followed by a piano rendition of said Moon theme), and with the ability to play the game using the original 8-bit music from the NES game.
That One Achievement: "Look Ma, No Spats". This achievement has you getting to the other side of the underground section of the Amazon, using only the pogo jump. While this was fairly easy to do in the NES version, Remastered decreases the amount of length between the top and the bottom, making this really harder to do, especially when the PC version of the game is running slowly. Did we mention the section is also littered with thorns?
What Do You Mean, It's Not for Kids?: A common criticism of Remastered (and the Castle of Illusion remake that was released a few weeks later) was that it was too difficult and wouldn't appeal to children. In addition to the Unfortunate Implications that younger gamers are too stupid and/or impatient to bother with a difficult platformer, the reviewers seemingly forgot that most older gamers were also children when the original NES version came out.
