I think we are at the very beginning of high changes, not only in terms of digital film, but in the way the movies will be screened, whether they'll be screened on phones, on computers - on everything.
I watched a lot of silent directors who were absolutely great like John Ford and Fritz Lang, Tod Browning, and also some very modern directors like The Coen Brothers. The directors take the freedom within their own movies to be melodramatic or funny when they chose to be. They do whatever they want and they don't care about the genre.
