Awful.
This flash is simply a waste of everyone's time. My time for watching it, the artist's time for making it, and Billy Mays' time for becoming an iconic enough figure to have tributes made to him after his death.
Other than the time being long gone for making tribues to Billy Mays, this was bad in the technical aspects as well. It's just a distorted picture of Billy Mays next to a stick figure crying over his grave. The audio is a distorted rendition of some of the late Mays' advertising.
It's bad and you won't lose anything by not watching it. And if you want to watch it, go ahead, it won't take away so much of your life that you'll regret it.
