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 & Cat
Broken Base: Quite a few ways even before the show first aired.
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.
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.
However some Les Yay shippers didn't mind so much.
There are various ways people believe this show or the people involved are to blame for getting various shows cancelled:
In the Victorious fandom there are people who blame Jennette McCurdy for getting Victorious cancelled are refusing to watch the new show because she asked for Ariana to join the show. They also aren't happy at Sam & Cat getting almost instantly another 20 episodes added to the first season order, giving it a total of at least 40 episodes before the first season is done, when Victorious only managed 58 over several years.
There are people who believe Dan Schneider and the Sam & Cat show is being misblamed for Victorious' cancellation despite Dan Schneider's reassurance that it is not the reason at all. Others take the view that Sam & Cat is the reason for Nick cancelling the majority of their live-action shows (How To Rock had its producer flat out say it) that were cancelled at the same time.
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 before it was even greenlit for production beyond 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 was 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.
Alongside that, the Victorious fans are pissed off that their show was confirmed to be cancelled, and even though it's been said that the show's cancellation was an executive decision, Ariana and Dan are blamed for wanting to do Sam and Cat, resulting in the show's cancellation. Some fans have since stopped hating the show following a Victorious character making a cameo (And Jade and Robbie being slated for a one-hour special), and are hoping that Victorious gets a Fully Absorbed Finale (Much like Batman Beyond did with Justice League).
The fandom of How To Rock hates the show for similar reasons.
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.
Goomer's stupidity has split the fans between those who think he was born smart and just suffered some bad blows to the head, and those who think he was born with some kind of condition.
Base Breaker: Sam's jerkass tendencies when they're played Up to Eleven again break the fans between those who think it's funny and those who want Sam to be punished once in a while, but everyone has admitted that at least the writers aren't forgetting who Sam was in iCarly (The same applies to Cat when she's particularly dumb). Also, thankfully, she's much less of an asshole then she was (Mostly).
Dice. He himself has been largely well-received, but the LiveJournal community often brings up how Dice's actor seems to be trying too hard to keep up. His fans defend Dice by saying that there are worse shows Nick has made with worse acting, say it isn't too annoying for any reason, or say that the iCarly cast wasn't perfect when they were young and that Dice's actor should be allowed to grow as well.
Goomer is this- some think he's cute and also pretty badass, but he also has an entry under The Scrappy below.
Cargo Ship: Sam and her motorcycle. Not so notable in the pilot, but Revenge of the Brit Brats and Motorcycle Mystery have lead to fans joking that Sam will soon want to marry the bike, and that it's ruining their hopes of Sam and Cat getting together.
Designated Hero: Sam, especially in "#MotorcycleMystery (For threatening to kill elderly people who had nothing to do with her bike going missing) and "#PeezyP" (For being a jerk to Cat and breaking several promises to hang out with the man who just bullied Cat).
Both Sam and Cat get this in #MyPoober. Despite the child in the episode having a genuine reason to keep her toy, Sam and Cat plan to stick the thing in a rocket, and when the girl swaps her toy with a pineapple stuffed with money, Sam and Cat have the gall to leave her in a graveyard. How the hell do they plan to get payed with no child to give to the parents?
Dude, Not Funny!: Cat's bibble addiction has been toeing the line since Victorious, but it finally reached this when we learned that she once ran out of money, causing her to pawn Nona's jewelry and they had to go to therapy just so Nona could forgive her.
Many felt that Mrs. Merr's comment after finding out Goomer was a fighter went way too far for a comedy show, let alone one aimed for kids.
Sam's actions in Peezy B have... alienated some fans, to say the least.
Nickelodeon in the UK clearly feels some bits can go too far - the shot of Cat jumping onto the hood of a moving car is cut from the channel's airings of "#FavoriteShow" (as is all footage of Cat on the car in motion, assuming there's any - this troper hasn't seen the uncut episode, but it looked suspiciously truncated). That said, it still turns up in the opening titles of each episode.
Fridge Brilliance: Why did Dice's mom make him a hair model? The money and publicity would be good for his business.
Fridge Logic: If Sam didn't like sleeping on the couch, why didn't she just fold out the bed like she did in #Pilot?
Because that was a different couch. A better question would be why Sam doesn't just sleep in Cat's old room, where I assume they got the extra bed.
Genius Bonus: At one point Sam poses as a nurse while in a hospital. A doctor then barges into the room and asks a lot of short clipped questions, to which Sam responds perfectly. Most are simple things anyone could guess: "How's her vitals? Respiratory? Fever?" but his final question is "Does she have a Babinski?" which Sam answers "It comes and it goes." To which there's a slight pause... before he says that's what he expected, then leaves. It seems nonsensical, but a Babinski reflex is something that is normal in babies but can be a sign of spinal injury in adults. It's fully possible for someone to have a Babinski reflex that "comes and goes" and therefore what it indicates be muddled.
Ho Yay: Dice gets this a lot. From his clingy, egg loving, friend in #TextingCompetition to Goomer, who really loves Dice's hair.
Iron Woobie: Dice has to go through a lot of hardships on the show (almost losing his best friend, having to dance for money, and almost losing both of his pets) but he's not miserable
Les Yay: In just the first episode the meter is broken, and its no surprise really since even the Promos that aired before the show started liked to mention how much Cat loves to hug Sam.
Sam and Cat actually share a bed in one scene. It's only because this is Nickelodeon that nothing more was made of it than the two of them lying next to each other. In the next episode they end up in bed together again, in a wrestle style embrass, after Cat tries to wake up Sam.
Nightmare Fuel: The Brit Brat's reaction to Sam "killing" Cat in Revenge Of The Brit Brats is more annoyance because one of the two promised the other that no-one would die this time. Think about that.
When Cat finds that her bibble's gone missing, she lets out several bloodcurdling screams, much to Sam's indifference. Later on in the episode, after Sam finds that her motorcycle has been painted pink, she angrily shouts out Cat's name and she evidently looks like she's going to be out on a manhunt.Even worse, Sam's "murdering" of Cat also qualifies as it goes from a shouting match to Cat screaming like hell as Sam "kills" her roommate.
Doll Sitting is... surprisingly creepy, for a comedy.
After Goomer's name was revealed to be spelled as Goo Mer, some fans call Cat/Goomer Coo.
The Scrappy: Goomer. Every scene he is in tends to make Cat incredibly saner and more tolerable in comparison. His appearances per episode also diverts the focus from the show's babysitting service plot. Also, remember how Dice used to be a peddler? Have you seen him try to sell anything since Goomer showed up?
Though to be fair Dice doesn't necessarily need to sell random stuff if he's going to manage a MMA fighter which should make him considerably more money.
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.
It can be argued Jade's future appearance on the show is an attempt at this too for the Cat/Jade shippers (After Tori and Jade, Cat/Jade is one of the more popular Les Yay pairings in the fandom).
