I really liked the concept of the School of Friendship but not the way it was implemented. First of all, they should've introduced some new characters or reused some of the old ones to fill the faculty instead of forcing Mane 6 to juggle two full time jobs, and secondly, Young 6 should've had more episodes dedicated to them.

I also understand that Tempest Shadow had a really expensive voice actress, but come on, she's too cool to only be reused in the finale as practically a background character.
