This was glorious! The most thrilling this King has ever seen, I was a the edge of my seat, Luna = OP, seriously, so many good things happened in this episode, praise to the writers. One of the best episodes ever. That Big Mac moment made my tear up for the guy, I think that is the most screen time he got in that episode. I feel like I watched Inception for a moment, But I do have some questions that need to be answered about Luna's morality and choices... Best Mid- Season Finale EVER! Let's Review! No seriously....

Story- Princess Luna's dreams are inhabited by the Tantabus, a parasitic smoke monster that turns her dreams into nightmares. During a dream where Luna turns back into Nightmare Moon and is defeated by Twilight and her friends, the Tantabus escapes into the six ponies' dreams. Luna enters each pony's dream to catch the Tantabus before it can grow powerful enough to spread its influence into the waking world. Unfortunately, it infects all of Ponyville when Pinkie Pie dreams of sharing ice cream with the whole town, requiring Luna to merge every pony's dreams into one in order to find it. Despite the townsfolk's efforts to help contain the Tantabus, it grows in size when Luna blames herself for creating it as self-punishment for her actions as Nightmare Moon. Realizing her guilt is what empowers the Tantabus, Luna is able to stop it by forgiving herself. With the Tantabus gone, Luna is finally able to sleep peacefully.

I have mentioned why I liked the story, but I will get into depth on it a bit later.... first I will discuss Luna. Luna's decision to keep such a force within her, knowing the danger it would cause is a bit... questionable. I know she explained it in the episode why she kept the Tantabus within her, but isn’t it a bit foolish to create a 'being', I guess Luna is a glutton for self-punishment... Whatever the case, Luna was awesome. And still is.

Animation & Sound- All of the dream sequences were awesome! I also liked the Big Mac Alicorn transformation, Larson strikes again... The dream sequences were done to perfection, the scenery at the end of Luna's dream looks so amazing, and the magic animation was done, all in all that was amazing job on the animator’s part.

The Positives
This episode was a thrill. I was kept at the edge of my seat, and I loved every moment of it, Rarity, her dream about the clothing monsters were the best in my opinion. Then theBig Mac Alicorn change-over was cool. Luna was at her best in this episode, unlike Celestia these days... and the story was pretty well executed. But that is my opinion on the matter. What do yuo guys think? Also Spike was meh in this episode, but at least he was. Also the continuity callback were so much, and Lyra Bon Bon cameo so yeah... Yeah!

Negatives
Luna's idea to create such a thing is out of the question, and the power of that thing was a bit too much, but I liked Luna's inner struggle. Also why blue smoke? like why? I see no point of it as smoke, as an individual entity would have made the confilct more deep, as Luna is litterally fighting her inner demon. But... this is entierly subjective to one's self so yeah, also apparently the dialouge was clunky... to me it was 'meh'.

Final Rank: A
One of the best Luna episodes since... forever, we get to see forgiveness play a role in Luna's anguish and the callbacks were so much. Big Mac shined like a star. The dream sequences were amazing, Rarity and Fluttershy being my favourite. Rainbow power makes a return and this episode was really good. But the episode was one of the best, and a thrill to watch.

See you next time folks... and foals and others....! Also why hituas! why!?!?!
