Rey is not even a Chosen One prophecy character, and just has Skywalker blood but is easily seemingly ROTJ Luke with no training. ESB Luke could not even handle two Magna Gaurds. Prodigious force ability for Anakin and Luke still made them train and learn to be effective. I was watching Screen Junkies, and even they called her the biggest Mary Sue of all the SW movies lmao. Honestly, I'm curious did you watch the movie? It really doesn't seem like it. I mean, I can understand people whining about the no-training, even though it's something most prodigious Force users never have a problem with (Anakin, Luke, Savage Opress, etc), but really? She doesn't know what the Force is or how to use it? Is that how she, without the all-important formal training that only the fans of Star Wars seem to care about (much less the writers themselves, lol), managed to invade Kylo's mind in response to him penetrating hers, and successfully mind trick a First Order trooper? Is that how she received a calling and Force Vision from Anakin's lightsaber just by being near it? Is that why she quite literally says 'The Force', and then closes her eyes to focus on it at the climax of her duel with Kylo? Because she doesn't know what it is or how to use it?

Rey is an untrained force sensitive who has used a lightsaber once in her entire life, and doesnt even know what the Force is or how it can be used.
