The rest of your comment like you said is "not for you anymore". That's all personal taste. It seems that the general public and many here (including myself) really like this show with the main critique being that it is too short.
Now listening to this version of The Magic is Calling makes me wish that this was the main theme of Disney Enchantment. It's such a great song and already sounds like it could have been in a nighttime spectacular.
Last night, a few groups of guest were using the rear staircase of the castle and walking up to the balcony and past the windows of Cinderella’s Royal Table. (Full video on Instagram by spanselphoto)
I believe those turrets, such as the ones in the hub were input to signify the reach of the castles forecourt and rear courtyard so theaming wise it makes sense.
I understand what you state fully, but I just don't see it being a new building. Either way, Disney will confirm what will happen and fortunately we will be having new entertainment on Main Street U.S.A.
The easiest and most logical place to place a "Theater" on Main Street U.S.A. is in the current theater. What would be the point of having two structures named "theater" that look very similar on the exterior?
They said on Main Street U.S.A. at the Magic Kingdom. Looking at the building, it's obviously the theater. You can even see the backstage gates that they use when the park is crowded on the left in green.
