What’s the TL;DR version
Ha! Yeah I woke up this morning and just had this stream of consciousness slip out of me. I did try to organize it so it wouldn’t be too jumbled, but I look at it now and it is quite long!
The short take is that I think Rey is about as good of a character as Luke was in the OT. They both have natural force abilities and good temperaments. I think it’s unfair that people call Rey a “Mary Sue” for her natural abilities and lack of training, because Jedi training (even Luke’s) was always really about personal character development.
