He’s gonna take a piss on the film.
xD. I like that. Actually, it’s a yellow color tint that is meant to replicate the colors of A New Hope.
As for the interrogation scene, there’s no real point to it, as the force awakens inside her when she touches the lightsaber in the previous scene. You could say it further develops her ability to use the force, but I found it more interesting to see her grasp the concept of the force on her own, without having someone trigger it. The other reason is, I found it more dramatic for Kylo to only reveal his face later, when his father asks him to do it.
As for the street slang, Finn yelling, “Did you see that?! Did you see that?!” just sounded like something from a generic modern action movie, not Star Wars.
If you have any other suggestions, please feel free to comment back. Thanks!
