- Alternate Character Interpretation: There's some implication that the costume designer that quit at the beginning was performing her own take on Writer Revolt with the last lineup of costumes. The costumes in question are just simple white shapes, and when confronted, the designer had no qualms about calling out Vignette for her constant waffling about the costumes before quitting at the end of Vignette's tirade, hinting that the quitting might have been planned and the costumes were just her deciding "Screw it" beforehand.
- Anti-Climax Boss: Vignette goes down pretty easily once the girls pony up. Rarity simply whips Vignette's phone once with an energy tendril, destroying it. Vignette then goes into a Motive Rant, and the girls talk her down.
- Ensemble Dark Horse: One of the background characters attracted a lot of attention for the simple fact that they might be G1's Megan Williams.
- Fanfic Fuel: Megan Williams, or at least a character who looks a lot like her, exists in the Equestria Girls' universe, opening the door to a lot of possible ideas.
- Hilarious in Hindsight: Fluttershy really is into death metal, donning the exact same dress and hairstyle.
- Les Yay:
- The Applejack x Rarity subtext is paper-thin. They're first shown waiting eagerly to hear they've been hired at a carnival so they can work together, laugh as they say the same things in unison, and are more upset that they won't spend the summer together than Applejack not getting hired. After their argument, their make-up includes blushing, held hands, looking into each other's eyes, and finally a big hug with Foot Popping from Rarity. Then comes the ending song, with the two singing a duet as they look into each other's eyes, and sing lyrics like "It's you and me / this is how it should be" and "behind that perfect snapshot / are the people who you love". Finally, the special ends with a Photo Montage, the last picture being of the group looking at the camera... except for Rarity and AJ, who are making eyes at each other and holding hands. When asked about it, Word of God directly admitted their conflict was written in the framing of a lover's quarrel.
- Fluttershy and Rainbow Dash travel Equestrialand arm in arm, like they're on a date.
- The group fears that if Vignette uses her phone on a large crowd of people and teleports them all into the White Void Room at once, they'll crush each other. While this is a legitimate danger to be concerned about, Never Say "Die" sucks out any ability to take it seriously when the girls keep using "squished" as the incident they're fearful of.
- The climax. Much like Forgotten Friendship, the girls undergo their dramatic magical girl transformation and combine their magic to... destroy a cellphone. While the magic whip is much more tame compared to the traditional rainbow lasers, it still looks ridiculous. It doesn't help matters that Word of God admits that it makes no sense in any narrative standard and they only ponied up to sell toys.
- Tough Act to Follow: The previous special involved the reconciliation between Sunset Shimmer and Princess Celestia fans have waited the whole franchise for which met those lofty expectations. Regardless of its own merits, this special lacked anything as compelling.
- Unintentionally Unsympathetic: Word of God is that it was intended that Vignette Valencia "wasn't aggressively snobby, just carelessly self-centered in a relatable ridiculous way". While she got the self-centered part down, she had no redeeming or likable traits and was just as bad before the magic phone ruling out it corrupting her, Nor did she have a Freudian Excuse for her actions, which they all but say could have killed people. This left most fans, and maybe even show staff, critical of just how Easily Forgiven she was.
- We're Still Relevant, Dammit!: A major plot point in the special is Vignette's borderline addiction to social media. Not to mention outdated slang like "Yas Queen" and Rainbow Dash dabbing. Though considering this is all coming from the villain, it's very likely intentional.
- What Do You Mean, "It's for Kids"?: Vignette has one very... suggestive video on her social media account.
