Angry Grimace
Two cannibals are eating a clown. One turns to the other and says "does something taste funny to you?"
If you were paying attention, she had a flashback where it showed Luke dumping her off on a desert planet, so she was probably born even more gifted than either he or Anakin were. And he and Anakin were incredibly force sensitive. Anakin self-taught himself podracing as a little kid, Obi-Wan and Qui-Gon were like 'wtf'. She is also missing all of her memories since she thinks Luke is a myth, except at the end where she seems to understand and they stare at each other, and he looks grief-stricken.
She's also far from a master Jedi, her lightsaber skills were crap, she spent 80% of the fight running away from Kylo Ren and then after he's had tons of blood loss and tries to convince her to join him, she gets in a few lucky strikes.
Rey learning the Jedi Mind trick in 5 minutes was a little silly (but the sequence was fun) and they established very quickly that both Finn and Rey were at least competent in hand to hand fighting anyways (with Rey beating up the goons and showing that the First Order were competent and trained at hand-to-hand combat).
