In terms of leaving a lasting legacy, reaching out to all parts of society and producing iconic stories that are re-interpreted and spun-off through the ages, the closest might be someone like Spielberg or Lucas. These are stories that endure cultural shifts and even direct cultural shifts.
But still, I doubt anyone's really a match for Shakespeare. None of today's so-called 'great' artists have had to operate in a time of massive social change. So it's hard to leave such a mark as Shakespeare did.
