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.
Broken Base: The cancellation caused the usual rumors for an unexpected cancellation- the main star didn't want to do it, the creator pissed off the network or didn't want to do it themselves- before Jim O'Doherty explained why- the network decided to cancel most, if not all, of its live action TV lineup, in favor of setting up Sam & Cat.
Fan-Preferred Couple: Go look up How to Rock fanfiction, you will notice there are more Stevie/Zander fic's then stars in the universe.
Fandom Rivalry: A bitter one with Sam & Cat after How To Rock's creator revealed that they were cancelled because of it.
Harsher in Hindsight: Kacey spent most of the series trying to stop and outdo Molly since being kicked out of the Perfs. She was able to beat Molly and get the last laugh many times, but their backstory in "How To Rock Christmas" reveals that this is exactly the type of behavior Kacey had towards Molly when she was queen of the Perfs.
Incidentally, this recalls the plot of the books.
Hilarious in Hindsight: Zander dancing with Grace in "How to Rock a Secret Agent" becomes this after watching Series/Crisis, where Max Schneider's character has a crush on Halston Sage's character.
Minority Show Ghetto: Only current live-action Nickelodeon show to have an African-American lead. (And cancelled after one season, no less.)
What an Idiot: Molly in "How To Rock A Music Video". Where on Earth did she get the idea that Kacey would accept having to play personal assistant to her just to get back in The Perfs?
