As per Starkiller’s opinion:- I think the magic of what Poppa is attempting with these additions is that if you look at it from the perspective of watching TLJ as a first time viewer there are hints and easter eggs that we would have come out of the movie and then questioned, debated, freeze framed, rewatched etc in order to develop theories for the story ahead?

The beauty and fun of it is that when Palpatine’s Return is revealed for TROS, these hints were always there if you were looking/paying attention but it wasn’t ever overtly spelt out.

As fans that’s the stuff we live for…because we like to feel we are cleverer or perhaps just simply care more about these details than general audiences do?
