Mine is a bit niche. Male anti hero protagonist revenge movies. Usually takes place in england. Always has a heavy criminal element, a good bit of violence and the lead usually dies in the end. Recent favorites include “Bull” “Avengment” and “Villan”. Not sure if this specific type of movie is a genre or not but there’s plenty of them.
Period dramas set in France. On one hand there’s the glitter and social schemes, on the other, justice and revolution.
That’s definitely niche! Great answer.
I’ve always loved The Scarlet Pimpernel starring Ian McKellen as the bad guy (Chauvelin? I can’t spell French worth a shit). It has all of the above. He was so good in that movie.
