There's absolutely no way an untalented person would be so hugely popular over such a long period of time. I think people tend to dismiss the popular with elitist narratives about how the commoners can never understand real art far too often. It's simply arrogance and refusal to accept reality to deny them. Not every talented person succeeds, but every person that succeeds must have talent. Luck and backing aren't enough to make art massively popular.
