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: Friendship Is Magic S3 E7 "Wonderbolts Academy"
Pinkie's behavior in this episode. Either it's funny, sad, or annoying.
This episode. It's either Merriwether's "best episode since Hearth's Warming Eve" or "So Okay, It's Average but least it's not Mare Do-Well since the whole episode is written better".
Draco in Leather Pants: It didn't take long for Lightning to get several fans who feel she has a Freudian Excuse for her reckless nature such as a personal tragedy in her past. Other feel she is a reasonable pony that underestimated how much danger Rainbow's friends were in and would have been remorseful had the others explained it to her better. This isn't as extreme as some examples because the Alternate Ending to the episode gives her a Jerkass Realization and has her accept that Rainbow was right.
Ron the Death Eater: Spitfire gets this treatment from certain fans for her Drill Sergeant Nasty portrayal, conveniently ignoring how this was clearly her on duty persona in contrast to her laidback off duty persona.
The Scrappy: Pinkie Pie is even more manic than usual self in this episode, and it can be very annoying; you just wanna say "Pinkie, checking the mailbox every 3 seconds will not make the mail come faster." At the same time, though, you've gotta feel sorry for her and wonder just how freaking fragile her confidence in keeping her friends really is.
Win Back the Crowd: For Merriwether Williams. Only one of her four episodes the previous season had been received favorably, but this one was heralded as a huge improvement, showing an understanding of the series and characters that she hadn't had before.
But that said, some have argued that she fell back into poorly written episodes almost right away with her next episode Spike at Your Service. (it also doesn't help that it's original premise had to be scrapped resulting in the final product coming across as rushed and lazy to some fans)
