What is Rey's most ridiculous Mary Sue power?
For me it is always going to be her perfection of the mind trick before she even realizes she has the force. I mean this is something that Qui-Gon Jin (a trained Jedi master) failed to use on Watto and Luke Skywalker in his prime failed to use it on Jabba the Hutt.
Yes I get it, women are strong, they don't always need men to protect them, blah, blah, blah I've heard it all before I don't need Star Wars to force (no pun intended) it down my throat.
It will be interesting to see what Mary Sue powers she develops in The Last Jedi.
