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.
Thanks to YouTube Poop, the common portrayal for Duke Onkled is a Butt Monkey who betrays the King every other day of the week, which is taken as seriously as his appearance. He's also seen as Depraved Homosexual, often with the King.
Justified as the Triforce of Wisdom promises The King will safely return.
Ganon:"You are my prisioner!"
Anti-Climax Boss: Every boss is killed in one hit from the weapon they are specifically weakest against. This includes Ganon, the final boss, who gets sealed in a book in The Faces of Evil and Wand of Gamelon. Even though the weapon he's weak against is only a book in the former.
Zelda's Adventure is very hard to obtain footage from because it can't be emulated, and demands huge prices on eBay.
Crowning Music of Awesome / Ear Worm: Say what you will of the rest of the games, but a lot of the music in Wand of Gamelon and Faces of Evil are very cool and catchy, if a bit incosistent with the Zelda series.
Oddly enough, when these games were first released, they actually had a fair amount of praise from reviewers and the few who actually played them on release. Good luck finding anyone who considers them anything above So Bad, It's Good today.
It also killed (For a while), any attempt to outsource any of Nintendo's core franchises to Western studios after this fiasco.
The King is only really important to the storyline of Wand of Gamelon, and not very much at that. He only ever shows up in the intros and endings of the games. However, he's one of the staples of YouTube Poop.
Memetic Molester: Thanks to one of his lines in Wand Of Gamelon made very questionable via Mondegreen ("Keep the cuntnote It's supposed to be "the runt" in chains!"), this incarnation of Ganon is seen as one. Not to mention there's the scene where he kidnaps a sleeping Zelda in The Faces Of Evil...
Ushrom's rather creepy mannerisms as well as 50% of his dialogue in his only appearance of the CDi games (as well as the entire Zelda franchise) being misinterpreted as something much worse has earned him this status as well.
Narm: If the creators intended these games to be serious, then goddamn everything.
Nightmare Retardant: Ironically, many of the bosses in the game fall victim to this. It's hard to be scared of the villains when all of them have Narmful designs, bombastic acting and just plain weird methods of terrorizing people.
Hilariously, the ordinary citizens are often truly frightening thanks to odd expressions and movements and their habit of moving in closer and invading your personal space.
Vindicated by History: Inverted, while nowadays these games are either flat out reviled or considered So Bad, It's Good by the Zelda fanbase. But would you believe that back when these games were first released they actually did pretty well with the game magazine Critics? Critics have praised the games for their animated cutscenes and voice work and thought it was a nice new direction for the series. (And even those who did give the game a negative review back then they generally more deem it as So Okay, It's Average.)
