You have several ideas here that need citation from sources, so I’d suggest you open with some quotes from Giannetti about Kane to set up your analysis. Then perhaps just take 1-2 scenes from Kane to show what interests you and add more detail to your analysis of these scenes. Finally, read the whole draft aloud slowly to make the sentence flow as you would say it if you were speaking to the reader. You’ve got good topic selection and source, but you still need to focus on paragraph structure and source citation.
