My comments weren't meant as a criticism of your essay. They were, if anything, an additional angle. One can interpret the video as an artistic work apart from anything personal about Alizee as I would expect most people to do. That's the way I first interpreted the video, but after seeing the other two videos that I included, it struck me that "Mademoiselle Juliette" might be a very personal statement.
So what are your thoughts on the other two videos that I included? The second video listed below suggest--not a subject--but a theme that Alizee is repeating.
