IIRC he thought Rose was a badass woman heroine in Titanic. I remember the first time I saw the film, I was horrified at how many people would have died by someone pulling the crap she did while the ship was sinking.
I suppose it does critique upper-class arranged marriages in the Gilded Age, but that's a ridiculously easy target, as is how the rich treated the not-rich (and still do).
(Yeah, "first time". I like watching it for the costumes when I'm sick. Don't judge.)
