That's insight i didn't have. And because i don't watch much at all of that sort that stuff i had no idea what sort of a character Norma Desmond was until you said what you said about her.
"For example, one of his favorites is Sunset Boulevard. He recommends it to people; even makes them watch it. And it seems he never for a moment realizes that HE is Norma Desmond."
Guessing he likely does see much of himself in her, and that's at least a good part of the reason he is keen to have others watch it.
