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: Sam And Cat
Broken Base: Quite a few ways for a show that hasn't even been filmed yet:
The two main characters are their own base breakers. Sam for being obnoxious and evil, and Cat for being incredibly stupid to the point of being Too Dumb to Live. Both characters draw major heat and adding them together makes it worse.
Those who wanted to see Jennette McCurdy take on a new non-Sam role often because of their dislike of Sam vs those who want more Sam as well as potentially more Sam/Freddie interaction in the new show.
People from the Victorious fandom who are blaming Jennette McCurdy for getting Victorious cancelled are refusing to watch the new show, or blame the Scapegoat Creator and/or the Network for cancelling Victorious because they wanted to do Sam And Cat instead.
Cat: I play a cop on the edge who makes his own rules!
Sam: No, you don't. That's not what you play.
Cat: And she plays a lonely doctor who's fed-up with the system!
Sam: I don't play a doctor, and I don't care about the system.
Cat: And together we fly a starship in search of friends and moondust!
Hype Backlash/Hype Aversion: Both stars of the show have a massive and sycophantic fanbase (much of which is from tweenage girls on twitter), and both characters have their own set of detractors, haters and people who simply don't like them. Add in the Fandom Rivalry aspect of the creation of the show and you get a nice big group of people who have refused to watch the show.
Fandom Rivalry: Where to start? This show has caused something akin to a multi-show Nickeoldeon fandom factional civil war and it's only filmed a pilot.
From iCarly fans: There is a split between people who wanted a new show (for Jennette McCurdy), and those who wanted Sam to get a spin-off. That also has elements of the iCarly shipping war involved, as people who want Sam back are mostly those who ship Sam and Freddie. After the finale of iCarly led to a Carly/Freddie Last Minute Hookup, the Seddie fans know that Sam being spun-off is their only chance at any revival for their ship.
There are also those who disliked the way iCarly was ended, and have chosen to avoid or boycott this show so as to not get sucked into Dan Schneider's trolling.
Carly/Sam shippers (or those who liked the pairing as a platonic best friendship) not wanting to watch Cat replace Carly as Sam's best friend.
From Victorious: When word initially came through about Sam And Cat, people were worried about how much work Ariana Grande would have to do, and if her character Cat would stay on the show. Fast forward a few weeks later, and they don't have to worry about that. Because Nick cancelled Victorious to make way for Sam And Cat. Cue outrage from all but the most hardcore of Ariana fans.
Old Media Playing Catch Up: After the Twitter/Facebook hybrid "The Slap" being featured on Victorious, the show seems to be heading even more into promoting twitter style social media, with the episode titles taking the form of #HashTags.
Even before iCarly has finished Dan Schneider was teasing the idea of a Seddie reunion on the show.
Jennette McCurdy and Ariana Grande's fanbases, which are best seen on Twitter, are being pandered to by having their characters spun-off into a new show while cancelling both the parent shows.
Ship-to-Ship Combat: The disappointing ending for the Sam/Freddie shippers from iCarly has turned elements of the early fandom for the show into a one-sided shipping war, with the Seddiers trying to push the idea of Nathan Kress guest starring, so that Creddie can be sunk and replaced with Seddie.
Testosterone Brigade: Jennette McCurdy + Ariana Grande = an audience not entirely consisting of preteen girls.
The Ship's Motor: An interesting usage of this trope, because Dan Schneider is teasing the idea that he might bring back Freddie Benson as a guest character on this show, to make as many Sam/Freddie fans from iCarly want to watch the new show as possible.
