Sailor Moon is not made by someone fond of America and someone who have Hollywood or American aspirations, CLAMP and Kishimoto are that so I imagine that it would have been more easier for CLAMP if one of their earlier works got animated and became dubbed prior to Sailor Moon.
It always bothered me that you don't see all of Sailor Moon's shoes in her first transformation. I wish we saw a movie version of their first transformations
Some mangaka have a favoritism to their English audience so their manga gets remastered there and those mangaka who are fond of Hollywood, unfortunately they aren't popular in the US themselves.
