Finn tries to use an old pickup line used by a legendary hero. Of course it goes awry when both A) Rey knows his real personality and B) the author of said pickup line overhears the convo.
To be honest, if we’re talking overly powerful Mary-Sue characters in Star Wars, Galen Marek/Starkiller is probably the worst offender.
But at least he had had extensive training to get to that point.
And that’s the real issue with Rey – it’s not that the things she does are particularly impressive, it’s that she acquires new skills as the plot demands with no practice or instruction, and that’s just lazy writing.
