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: My Little Pony Tales
Aborted Arc: One episode introduced mysterious pegasi (one of which introduces herself as Brightglow) and an alicorn who's bodies are noticeably brighter than the other characters and dotted with stars. The alicorn performs magic and they appear to know Patch. They are only seen for one episode, only to never be brought up again. Still, it does make for good Fanfic Fuel.
Anvilicious: A good part of the time, anyway. While a few of the aesops were handled with surprising subtlety, most of them fell into this.
Germans Love David Hasselhoff: The only plausible reason why two of the ponies from this series got a kiddie ride made after them and the show has seen home video releases in the UK and Australia. And in Australia's case, it was a complete release of all 26 episodes spread across 4 volumes. The series received no video releases in its home market, the U.S.
Tear Jerker: The song Off You Go from the episode Gribbet. You try not crying, especially just after losing a pet, or giving away something of sentimental value to someone else.
The Scrappy: Ace is the most hated character for not only treating girls like crap and using them for his own purposes (only made worse by the fact that the show is aimed for girls) but for also being a Jerkass in general.
Unfortunate Implications: The episode "Stand by Me". While Teddy is usually a Jerk with a Heart of Gold (especially around Sweetheart), during Sweetheart's song about Teddy's true self, we see him physically and emotionally assaulting her and then making up for it a little bit. It makes Sweetheart look more like a beaten housewife than Teddy's savior.
Their relationship in general, thanks to Aesop Amnesia. Teddy is intended as a Jerk with a Heart of Gold, but in every episode where Teddy is featured heavily, we start out with him being a jerk and have him learning to not be a jerk in the in the closing scenes after much pushing, or resorting to blackmail. (No, not the same incident mentioned before. Sweetheart had to resort to fighting fire with fire when Teddy was holding Bon Bon's diary hostage to make her his personal slave.) If you have to work that hard to get a guy to stop actively making your life or your friends' lives hell for two minutes, and this is a regular occurrence, you are not the one person capable of seeing the true self of a Jerk with a Heart of Gold; you're the Love Martyr to a Jerk with a Heart of Jerk. In Real Life, Sweetheart and Teddy are a textbook example of what a bad relationship looks like about a week or two before Sweetheart starts "accidentally falling down the stairs" a lot... including or especially Sweetheart's "He's not a jerk, really he's not, he can learn to be different, really!" bit.
Also, more than half the time the girls are essentially saying to leave her abuser this instant (often a difficult task in it's own right) or they will drop Sweetheart like a hot potato and leave her to her fate without a second thought. Bonus points because it makes their friendships look shallow and exclusive.
"Shop Talk." Should we really be teaching our kids that blackmail is the best answer to their problems?
Any episode with the girls Vs. Teddy. Jerkass though he is, they are rarely much better whenever he's in the picture, often jumping to conclusions and twisting facts to fit their bias. They're almost always putting poor Sweetheart in unfair situations and threatening to end their friendships with her.
