Favorite topic- I love films!
I tend to love films with some strong social commentary and controversial viewpoint on a topic. It could be any topic- as long as it's culturally relevant and progressive.
For example I really loved some films with French actress Catherine Deneuve in the 60s. She starred in this CHILLING psychological film by Roman Polanski himself, called Repulsion, where an extremely paranoid woman is repulsed by men and sex but secretly entertains fantasies of being raped while she is left alone in her apartment.
She also played in another 60's movie Belle du Jour, where she plays a Parisian housewife who daydreams of all kinds of wild sexual trysts, and becomes a day time prostitute where she could explore her sexuality while her husband was away at work. I love a cinematic work that explores the complexity of people's needs and desires, especially a woman's sexual desires, as imagine in the 60s, this wasn't even something possible to discuss openly! Or that women were even seen as having sexual agency.
