That they're mediocre shit games, like most of this kiddie "best ever" franchise.
"Mediocre" and "shit" are mutually exclusive descriptors. If you're going to edgelord it up successfully you need to first level up your English language skill.
Oracle games are pretty good although all the gimmicky gamelink bullshit can fuck right off.
Minish Cap also has some pretty good dungeons, even though the game as a whole shares a lot of the same high-level design flaws as Skyward Sword
Mediocre would be oracle and Minish Cap. Shit would be OOT, Wind Waker, Twilight Princess, Skyward Sword, and Spirit Tracks. That's my experience as someone who's played almost all of them.
With Minish Cap, you could tell the talent behind LTTP and the earlier games was no longer present. The game is easy, the weapons are dull, and the gameplay isn't quite there. Given that all you need to do to finish these dungeons is go through the motions, none except one or two are entertaining. That dungeon where you gain jumping in Link's Awakening is much better than any in this game.
