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.
Fan Dumb: Among the complaints Christian received for his series range from not being accurate to Portal lore, to having Half-Life references in a Portal-related series (despite the two franchises sharing the same universe), to ruining the original video game simply by putting ponies in his series. Christian loves to call these people out.
Fridge Horror: This is a crossover with Portal. You will recall that the Portal storyline occurs well after the Combine's takeover of Earth in Half-Life 2. With this in mind, what's happened to Equestria in the ten years Twilight's been in stasis?!
The Woobie: Rainbow Dash. To wit, she's outright maimed by DISCoRD, is forced to go through painful surgery without anesthetic to be rebuilt, something she didn't want.
