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.
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.
