America's Genghis Khan - Citizen Kane (Part 3)

We are roughly two thirds into the movie, and I can't help but think perceptions about him are a little skewered; every time the reporter interviews someone new, it's nothing but the negative. Does Kane really have not a single friend in the world?... This is what an amateur writer thinks; it is better to move on to some astute observations.
Ever since my first post, I wondered what it is he did for her that Susan went from being an Opera star to a night-club singer. I confess, my impression was that she was a starlet before the two of them ever met, though it's now been proven she just happened to work at a music library on the side. Mr. Bennett once told us that the aria she sings for him is the Bride's song from The Barber of Seville; I thought this was the opera Susan performed, but the costumes proved me wrong. Instead, it looks like she is singing something out of Cleopatra or Aida. It's a strange decision on Orson Welles' part, but then again, the grandioseness of the situation supports the materialism theme.
Mr. Bennett also mentioned something about stereotypes; while he touched upon Mr. Bernstein (who has a slightly bigger role than I previously thought) and the black band-leader, he has forgotten about the music teacher. It's probably just me, but his over-the-top reactions, his greasy hair, and his constant screeching make him into a stereotypical Italian. Maybe I am reading too much into it, but this is how I see it. It's also clear Susan isn't enjoying this one point; in fact, she is far more vulnerable than Kane ever will be. It's not that she sounds like a dog when she sings... It's just that he is far too controlling and the poor girl knows it. The viewer already knows the rest.
From the tone of her voice, I though it was Kane that left her out for garbage, but it was actually the other way around. Even Charles Foster Kane is not that big of a jerk. Then again, he DID cheat on Emily, and we already know what happens to her and her son. They probably don't show it yet, but they will soon.
If my guess about Rosebud is right, everyone else is not only in for a big shock; anyone expecting anything big will also be in for a big disappointment.
