A few other critics have noted the lack of dramatic agency of the Finn character in nominal configurations such as: his inability to comprehend “droid speak”, “Wookie speak” and other languages that come easily to the White characters; inability to pilot spacecraft; lack of weapons knowledge even though he was a Stormtrooper; and finally his lack of knowledge of “the resistance” when in fact as a Stormtrooper he would have known whom the Empire considered its enemies. These nominal inabilities are contradicted by Finn’s ability to wield a light saber with no training; his courage in various battles; his decision to leave the Empire; his choice to return to participate with the rebels of the resistance.
This right here was the worst part of it.
They keep highlighting that Rey can do ANYTHING. Speaks all the languages, can fly ships, can fix anything, can fight, has the force, etc.
Meanwhile, the only actual "wins" this dude gets in the movie is blasting a couple of tie-fighters, and even one of those fighters comes down because the gun is stuck, and Rey does this amazing maneuver that puts the fighter right in front of his sights.
Not to mention...he works in SANITATION.
Movie was straight up racist. He's basically a Kevin Hart type...that's the best way to describe his characterization.
