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.
YMMV: Monster High
Alternate Character Interpretation: Is Spectra just a know it all gossip with nothing better to do or is her past so traumatic (and possibly guilt-ridden) that she blocked it out to the point of not actually remembering it and surrounds herself in the lives of others because of this?
Creator's Pet: Some fans are starting to see Draculaura (and to a lesser extent, Clawd) as this.
Ghoulia has been largely the fan favorite since her first appearance, which still remains. Her original doll easily sold for 4x its retail when released onto ebay. Mattel took notice of this and gave her 6 dolls in total for 2011, including the SDCC exclusive, giving her nearly as different versions as Frankie, Clawdeen & Cleo, two of which are only available in multipacks that fans have no quams about purchasing (despite that one is a repackage of 4 old dolls included with her) exclusively for her.
Clawd and Heath also had quite a following, so much that both moved up to being main characters, and Clawd gets to have his own doll in a 2-pack with Draculaura.
Fan Dumb - a noticeable portion of the fandom dislikes that Operetta isn't more in traditon of the style of the original Phantom in both styling & personality but both of these were hinted at in her early mention.
Guilty Pleasure: To quite a few older teens and adults that don't even collect dolls.
