I notice you didn’t compare Rey with Anakin winning the podrace (no training), or with Luke using the Force to make a shot “that’s one in a million” (no training) as that would rather count against your Mary Sue argument.
Rather you go on about Luke having had a hard life - in fact Rey has had a far harder life than Luke. She raised herself as a scavenger and lived alone in a shanty. Luke had a relatively secure home life and upbringing. When Rey does finally make a connection to a Father figure that she has desperately wanted she sees him killed before her eyes… I’d say that qualifies.

Don’t you want Rey to be the best character she can be? Do you think she is?
I think she is too good to be true and the lack of vulnerability she has makes her less interesting to watch.
