'True Detective' would not pass The Bechdel Test.
In terms of tackling different subjects, I can't really think of anything I wouldn't want to try; that's the fun of it right? Each new style brings new challenges - not that you shouldn't focus on one and master it, but it takes so long to make a film, you just want to have some variety.
