One of my biggest complaints is that the personal stakes are too high. Sweetie Belle’s friendship with the other Cutie Mark Crusaders has been tarnished to a degree that I don’t believe can never go back to normal. Also, when Athena uncovered the truth and ruined Fare Devotion’s relationship with her son, I was upset when Apollo and everybody else ganged up on her without explaining how it should have been handled differently, as if she shouldn’t been doing her job.
And I don’t mean to contradict you but I’m not sure how the continuity of this series will be compatible with FiM by the end when so many characters already hate each other this much.
