One Bad Apple has been given mixed ratings and reviews. It's been hated for its mean-spiritedness, which I honestly have to admit was a major flaw with this episode, and at times it's been loved (or at least liked). But I honestly really get why anyone would call this episode good. As for more me, I feel more meh towards it...
Apple Bloom's cousin Babs Seed visits Ponyville. Though Apple Bloom, Sweetie Belle, and Scootaloo try to welcome her into the Cutie Mark Crusaders, Babs instead joins with Diamond Tiara and Silver Spoon in teasing and hounding the Crusaders. The Crusaders try to get back at her by booby-trapping a parade float that they trick Babs into driving, but learn at the last moment from Applejack that the reason Babs is visiting is that she herself was bullied by others back in Manehattan. The Crusaders save Babs, and together apologize for their actions. Babs joins the Crusaders and defends her new friends from Diamond Tiara and Silver Spoon at the train station before returning home.
It's only in my okay category nowadays, but because of what Crusaders of the Lost Mark did for Diamond Tiara, One Bad Apple isn't episode I will consider to be one of the worst anymore. Flawed for its mean-spiritedness as I said, the episode does have other problems. The plot was terrible at first, and despite that it's still unbearable for me to sit through it's even more understand on the bullying aspect of Babs, Diamond and Silver Spoon. The message came across badly along with some of the writing. But the positives I do have to give it have to be the song of Babs Seed herself and the part of her becoming one of the Crusaders which was a great pleasure considering the fact that Babs is an underrated character in MLP. Nothing to say about its animation or voiceovers as they're both spot on as always.
So I might understand some of it nowadays, but since I still can't stand most of the moments throughout its pacing, One Bad Apple is no longer bad, but is only worth listening to and not watching the song and the CMC clubhouse scene before the last minute or two is the only part in my eyes that is worth viewing at some points.
