YMMV / My Little Pony: Friendship Is Magic S6 E2 "The Crystalling – Part 2"

• Accidental Innuendo: The Bronies React video of this episode made a big deal about the image of the crystal shard entering the crystal heart. Toodles' reaction was to quote the refrain from "What What (In the Butt)" by Samwell.
• Base-Breaking Character: Flurry Heart. Some fans deride her as annoying, overpowered, odd-looking, reminiscent of the criticisms of "Baby Cakes" (as well as comparisons to Poof, another criticized Goo-Goo-Godlike), and responsible for the Crystal Empire being in danger yet again. Other fans accept her as cute (especially in contrast to the creepy designs of past baby Ponies), less overpowered than expected, and surprisingly tolerable. The fact that she's given a Power Limiter at the end also helps.
• Captain Obvious Reveal: Sunburst lying about being a wizard is quite obvious to the audience.
• Fanfic Fuel: Sunburst's time at Celestia's School for Gifted Unicorns.
• Hilarious in Hindsight: The fixing of the Crystal Heart was a major plot point in A Different Perspective which was 1.5 years before the Season 6 premiere.
• Memetic Mutation: Princess Dumbo^explanation  Due to her large wings, it became very popular for fans to compare Flurry Heart to the titular character from Dumbo.
• Narm: In the Previously on… recap of the first part, when Twilight Sparkle points out that the storm is coming and the characters are all facing certain doom if they don't fix the Crystal Heart, there is a blatant use of the generic crowd gasp Stock Sound Effect of the ponies' reaction that actually wasn't there in the first place. DHX crew, writers, do you want us to take this seriously or not?
• One-Scene Wonder: Night Light and Twilight Velvet steal the show when they suddenly speak for the first time.
• Rescued from the Scrappy Heap: Many people have softened up on Starlight Glimmer following her plights through the episode, desperate to help Sunburst and the Crystal Empire after her previous actions and doing a nice job at pulling it off thanks to the others' advice of friendship, especially Spike.
• The Woobie: Sunburst. He turns out to have a case of Dream-Crushing Handicap regarding his magical ability — and worse, his immense magical knowledge makes him fully aware of it — so he ended up becoming overwhelmed and living an insecure, reclusive life. Fortunately, he's able to not only fix his social standing, but also put said knowledge to good use after all in the end.
