I think that one was more a case of the anime getting ahead of the manga, but Sailor Moon in general is a minefield of changes for most of the above reasons.Miaka-chan said:The best example of this is Sailor Moon, the entire Alan and Ann (Ail & An) story arc from the "R" season was invented by the anime writer
Besides, I liked the first part of R, and the movie. Maybe Takeuchi was just upset that the anime writers were clearly having more fun writing their stuff than she was ...
