Thinking about it some more, watching it kind of reminds me of Disney movies. Maybe its because of the singing and character developments ¯_(ツ)_/¯
If i may add a recommendation, since you said you showed interest in Rarity, you could probably check out: [season 1 Episode 14 - Suited for Success]. One of my favorite because the character actually seems relatable and real, plus there's a song in it too Same goes for [season 2 Episode 09 - Sweet and Elite].
