What is art? Anything created by a human. Art can be very ugly, and shallow, and stupid, and pretentious, and meaningless, and spiteful, and so many other very human things we'd rather not say it is. That doodle a 5 year old lovingly scribbled is just as much art as the terrible TV show you watched that was clearly just made to make money.
What is good art? Now that is an entirely different discussion, and one that will ultimately come down to subjective reasons, because we will all see 'good' as different things.
