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.
Big Lipped Alligator Moment: Mother Nature's song introduces the eponymous character. Other than that, it's pretty pointless and is probably the least remembered song.
In fact, the character as a whole is rather pointless, since after her scene, which is almost entirely self contained, she just sort of disappears until the end of the movie to congratulate Snow White.
"I'm Bad" is an even better example. It comes right the hell out of nowhere and has absolutely nothing to do what had been going on in the scene until that point. Scowl just flies down from his window perch after Maliss leaves, lands on a table, and starts singing about how he's "bad". A rap number for Ed Asner. It ends just as suddenly as it began, and no one makes even a passing mention of it.
Cargo Ship: Blossom. The Mirror. Though since he is sentient...
For a more serious note, Lord Maliss is a legitimately threatening villain who can turn into a dragon.
Fan-Preferred Couple: Mmm, sort of. A lot of fans prefer Snow White to be paired with the Shadow Man. Kinda a Subversion since the Shadow Man is the prince under a spell, so really they just find the Shadow Man design and his shier personality more appealing.
Foe Yay: Lord Maliss and Snow White. Seriously. It doesn't help that the final showdown has a very BDSM vibe to it.
Also, Maliss refers to the Prince as "pretty."
Fridge Horror: Look closely at the statues surrounding the courtyard near the end of the movie. Quite a few of them were the goofy Mooks that were singing during Scowl's "Bad" song. And when Maliss is defeated and the cloak is destroyed, none of them change back to normal.
Narm Charm: Like the previous Filmation animated film, the Narm could be part of the fun.
Muddy:GET THAT SHADOW MAN!!!
Nightmare Fuel: It can be pretty unsettling. Especially the cape that turns people into stone.
There was also the image of the dead queen's face appearing in the mirror, which makes for a pretty effective Jump Scare if you don't see it coming. The Mirror, who conjured up the image in the first place, hangs a lampshade on the creepiness.
