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 S4 E7 "Bats!"
This comic, posted soon after the season 3 finale.
There's also Nosflutteratu which was posted a year before the episode aired to the day.
An episode made for Halloween that premieres around Christmas, which has a song that pays tribute to Danny Elfman. Hmmm...
The giant apple, previously seen in the parody Equestria Girls videos.
Informed Wrongness: Applejack. While she agrees with Fluttershy in the end, her initial position, that keeping the bats around risks destroying the farm, is an entirely valid argument. As seen below in Strawman Has a Point, Fluttershy's plan doesn't really address the problem at hand, yet AJ is treated as being in the wrong for not initially going along with it.
Rewatch Bonus: You might miss it the first time, but Fluttershy's cutie mark changes to bats when she's a vampire.
Something ignored by the episode was that Fluttershy's proposed solution didn't actually address the problem; The vampire fruit bats would continue to eat too many apples and ruin the ones that they don't eat. Keeping them in one place just makes things worse for Sweet Apple Acres, as the vampire bats would be forced to stay until they ruined the entire farm and then either left or starved. The promised long term benefit to the Apples would be unlikely to pan out, either, as they already have more apples than they can deal with, and already survived a vampire fruit bat attack, meaning that they're using trees grown from enhanced seeds.
They Wasted a Perfectly Good Plot: The episode could have easily focused entirely on the conflict of Applejack wanting to get rid of the vampire fruit bats vs. Fluttershy trying to find a more humane approach to the situation. Yet, given how everyone else pretty much sides with Applejack's idea (not to mention the hand wave to explain where the rest of the Apple Family was during the episode), it feels like "vampire fruit bats invading Sweet Apple Acres" plot point was only there to serve as a set up for turning Fluttershy into a vampire.
Wangst: Fluttershy's constant complaining about using the Stare can come across as such, since she was never shown to be this reluctant about doing so, and as noted above, comparable things have been done in earlier episodes without her batting an eyelid.
What Do You Mean, It's Not Political?: With the debates about the species’ drawbacks and benefits for the farm’s economy, Fluttershy’s communication issues with the bats, and the general rhetoric used in the debate, one could think they were discussing the issue of immigration instead.
