As usual your arguments and example clearly illustrate the point you are making. It is the point that causes me discomfort. To edit out the cultural elements to extend the life of a work limits the power of the author to create. It's like a homogenizing process that extends shelf life of a product, but diminishes the texture and flavor. Of course, the target audience of these writers are high school students. However, including the weirdness is how people learn about history and culture that change quickly. It challenges the reader to go beyond just today.
Personally, the video's you chose were excellent and relevant to the point. I was thinking about Romeo and Juliet before you even mentioned it in the essay. That work is so wonderfully written that it has been retold in many different ways including Zeffirelli's Romeo and Juliet as well as Romeo+Juliet.
I did enjoy the essay very much even if I have a slight disagreement with the point. Thanks @Comicality!
