WHAT.
“Phasma originally had another badass moment. The scene took place chronologically after she battled Finn on Snoke’s ship, right after he smashes the hole in her helmet. A group of stormtroopers corner Finn and he tries to get them on his side, saying that they can join him and escape Phasma’s grasp, just like he has. Finn says that she’s really a coward who sold out the codes to Starkiller Base. He pleads with the First Order squad to escape with him. The stormtroopers all look at each other…and in a moment borrowed from a Sergio Leone western, Phasma pulls out her blaster and guns down all six or seven stormtroopers herself before they have any time to react. It felt like a tribute to a classic western shootout, but for whatever reason, it didn’t feel right in that moment of the movie.”
