I loved this episode. While it had a very weak plot that didn't make much sense, I found joy in most of the fanon becoming canon. The one disappointment I had was Vinyl not getting a talking part, but the whole scene with Octavia and Vinyl creating music in the same house as roommates made up for that. I loved the voices for the most part. Dr. Whooves, Octavia, Bon Bon and Lyra all talked like how I imagined them to, so I am more than happy.
I also really liked Luna and Celestia being a little rude to eachother. It seemed pretty realistic, like how real siblings would sometimes not get along, especially when nobody's looking.
