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 Aesop: Considering how often Trish bullies and harasses others, the main aesop in Beauties and Bullies fall a bit flat.
Critical Research Failure: In "Costumes & Courage", they at least get the most basic fact about Charles Lindbergh right - but then veer right into "so wrong it's bizarre they even thought they could get away with this unless They Just Didn't Care" territory by mentioning that he invented the artificial heart. A five-minute trip to That Other Wiki would've shown otherwise.
Crossover Ship: Since the All Star New Year special it's become popular to ship Jessie and Austin (even though she has to be several years older than him).
The canon ship from that special, Emma and Austin, is pretty popular too.
Fan-Preferred Couple: The pairing is in the title. This pairing is so popular that Ross Lynch and Laura Marano, the actors themselves, ships it as well. It finally comes to fruition in "Partners & Parachutes", unfortunately, by "Couples & Careers", it didn't end well but many fans feel that canonizing the couple has effectively destroyed any interest in it. Luckily they are now back up by "Last Dances and Last Chances", and even confirmed in Records and Wrecking Balls.
Girl-Show Ghetto: Averted by using an equal cast of two guys and two girls, giving both the male and female lead important roles and singing time, making Ally an Adorkable nerdy girly girl and Austin a cute Nice Guy to attract both male and female viewers with eye candy. You can take the viewpoint that the show is slightly shifted more towards girls because Ally is just barely more of the lead character than Austin is due to Ally's music store being where the majority of the plot takes place and that it was Ally the audience was introduced to first. However, Austin's name is first in the title and all of the characters are primarily focused on advancing his singing career. They are even referred to a "Team Austin". Not to mention, the show is more a vehicle for Ross Lynch than Laura Marano, and lacks the Double Billing for them.
Hilarious in Hindsight: In December 2011, the episode "Kangaroos And Chaos" aired, with Austin singing "A billion hits is what I'll get". In December 2012, another artistdoes get a billion hits.
Hollywood Homely: A rare in-universe example: Chuck has been through no less than three girlfriends and has been asked to the prom five times. What makes him an in-universe example is that characters themselves treat him as a Cool Loser and are surprised that he's such a ladies' man.
Like You Would Really Do It: The idea that Austin would permanently lose his voice in "Successes & Setbacks" was never believable, since that would have reduced the show's premise to a big pile of rubble.
Ally actually leaving to go to the music school in New York in the season finale "Albums & Auditions". As the show was renewed there is no chance they'd have Ally leave for any permanent amount of time.
Surprisingly subverted in the next season finale. Austin, Trish, and Dez actually end the episode off separating from Ally, but in the first episode of season 3, she and the others reunite.
And subverted again in the next season finale. Even if it means being separated from Ally again, there's no way Austin would jeopardize his contract with Jimmy Starr, and thus the entire premise of the show, would he? And yet that's exactly what he does along with Dez following his girlfriend to California.
Dez. The problem with him is that he has bad comedic timing, and tends to ruin moments. It got worse after his actor got his own segments that play during commercials, making him come off as a Creator's Pet.
Trish, for her mostly selfish behavior. She also has it out for Dez for no particular good reason. She showed excitement at the prospect of him having his life threatened by sharks and eagerly tried to feed him to an alligator once. While Dez is a fellow Scrappy, it's too jerkish to be considered a Take That, Scrappy!.
Take That, Scrappy!: The imagined universe where she became a superstar in Austin's place has her act even more selfish than normal - this causes her fans and almost everyone around her to disown her.
They Wasted a Perfectly Good Plot: Many viewers felt this way when the writers ended Austin and Ally's relationship all of a sudden. However, their relationship picked up again starting from Last Dances & Last Chances, but not without a few obstacles along the way.
Unintentionally Unsympathetic: Trish, in "Beauties & Bullies". Sure, other students mock and tease her, but she has been doing the same thing to others since day one. So, it's less like that she's being a victim of bulling, and more like she can dish it out, but she can't take it. This is technically karma for her.
Vanilla Protagonist: Surprisingly averted considering how easy a Straight Man (i.e. Ally) lead can slip into this in the kid-com genre. The reasons could include that only Austin and Ally sing, ruling out the intra-fandom rivalry that other shows like Victorious suffer from. There is also no realistic opponent to the Austin/Ally 'Auslly' Shipping pairing, which would cause Die for Our Ship in the event of a lopsided Fan-Preferred Couple that does not include Ally. Finally with such a small cast of four main characters, there is no room for a typical overshadowing Ensemble Darkhorse to suck all the popularity on the show away from the main two cast members.
The Woobie: You can't help but feel sorry for Austin in the first two episodes of Season 4, because he still can't make music. This is also a case of a gender-inverted Fallen Princess.
