An episode that I was looking forward to but also dreading on learning the synopsis, for that of seven season, where we get to see the focus placed on Princess Celestia though in this case with her younger sister. Signs, yet a few things prevented me from enjoying it though I wish I could love this episode.
-------------------------------------------------------------
First, I did not buy the premise at all. Celestia gave up her sister for a thousand damned years, living with the guilt and loneliness all during this time with the Summer Sun Celebration actually being a painful reminder of what she had to do. I'm sorry, but in my honest opinion I do NOT see the princess not appreciating her sister.
Second is that apart from arguably the dream walking aspect which I feel strongly would have had to been an ability Princess Luna gained after being redeemed by the Elements of Harmony so that she was no longer Nightmare Moon, Princess Celestia has done her younger sister's job for a thousand years. Meaning she should know how hard the job can be.
Third, Starlight. Now since I have not been active on here for a very long time many may not know my feelings on her but while her introduction was enjoyable the way the writers handled her reform and all the other nonsense that came with her return. I don't like Starlight, the way they handled her reform left me having very bitter feelings for her. In general even, especially when it comes to her power and skill in magic with the spells she has been able to pull off with that of her ease in doing so.
I feel this episode should have been focused on Celestia, Luna, and Twilight Sparkle. Without Starlight Glimmer playing any part in it or in helping the Royal Sisters with the issues they were having. She knew the sisters best, having been Celestia's student and the first to truly befriend Luna. Starlight, she ahd no connection to them nor did she know them.
Also, almost forgot, I was annoyed that Starlight had any connection to the Cutie Map where it could send her off on missions. She never wielded any of the Elements of Harmony so she should not be called on for something the Mane Six should be able to do, and the Cutie Map should be special of their friendship.
