With just a couple exceptions, I consider all MLP episodes entertaining and a cut above most other animated series. By an objective rating, the vast majority could earn four out of five stars or better. But I think it's only fair to judge the stories by the standard of their own series, so I've scaled the episodes to create five groups of about-equal number, except for the shows at the very top. These form the Genji tier, which contains only the top one or two episodes per season. The Crystal tier designates the other real masterpieces of the series, the shows that have managed to outdo the series premiere. The Diamond tier are all great episodes without significant flaws; some are simply a bit lighter fare than the powerhouse Crystal episodes, but they're solid and entertaining (i.e, both strong and shiny). The Gold tier captures the middle group, still entertaining but a little softer, perhaps with significant minor issues or else simply outdone by many other episodes. The Iron tier contains episodes that, while still strong in certain ways, fall below the average for various reasons. The bottom Leather tier are of mixed quality or are weighed down by major issues, usually character and messaging problems.
AN EPISODE'S TIER MAY CHANGE when ranked alongside later episodes! If an episode is followed by ten episodes that rank above it and two that rank below, it will move down ten spots while the boundaries between tiers move upward to keep the same number of episodes in each non-Genji tier. That may cause the episode to fall into a lower tier than it previously had. For example, Keep Calm and Flutter On originally got a Golden Vest, but since 22 fourth-season episodes received a higher ranking, it's been pushed down into the Iron tier. My perception of the episode has not changed (if anything, it was enhanced by the fourth season's handling of Discord), but it's simply been outranked by the other stories. I can edit the text reviews to indicate the new ranking and armor, but the videos resist editing and so will still reflect the episode's tier at the time the video was created.
