I prefer Rey Kenobi
Why?
Mostly the continuance of the family motif but in this case the main protagonist wouldn’t be a Skywalker.
To continue the rehash tradition and expand it on trilogy level? If EP8 reveals that Rey is related to someone we already know, this will be downright ridiculous.
Yep…rehashing elements from the OT which was primarily built on rehashing rehashed stories that have been told in different ways throughout mankind.
Also they could have Rey learn who her parents are in IX and in a completely different way from how Luke learned in V.
