All the good movies and music have already been made.
Good music and good films could be made. But they will not be made.
Mostly I tend to agree. That's why there are so many re-makes. However, Tarantino's "Once Upon a Time in Hollywood" is outstanding, although a little long. Tarantino and M Night Shyamalan produce interesting takes on old movies with believable twist endings. Plus, they write, direct, and produce their own original material.
