Also I have some significant criticism I have for him is that he isn't really addressing his critics' point (or at least the most substantial version) in his newest video and it eats up about an hour of time.
When people bring up an objection towards an objective way of valuing or analyzing a movie their essential issue is that any objective approach can be dismissed because of the subjective nature of art. If you want to defeat that point you'll need to make an argument as to why art is not subjective (as in some criteria by which it can be appreciated) or demonstrate the value of your "subjective" standard.
Personally, I would've just ignored your critics in for this series because I don't see how that section adds to your analysis of TFA.
Honestly I think you are right. No amount of analyzing,nitpicking deconstructing is going to influence someone who only views art(video games,movies books ect.) as a form of entertainment or escapism. I think he might not grasp the fact that all of his "DEEP ANALYSIS" can just be hand waved away by some dude saying "I don't know i enjoyed it and though it was good." Objectivity doesn't matter for much when it comes to something that is highly subjective as Art and will subjectivity is subjective. You will always find someone who enjoys a shit movie/video game/book and they will honestly tell you they think it good.
