The last decade or so in pop culture has really been a nostalgia treat for folks around my age. Our sentimentality for intellectual properties such as Batman, Star Wars, Jurassic Park, Transformers,The Conners, Will & Grace, etc. has been indulged to the nth degree. That's a positive, I suppose, though there is a downside: what will the youth of today have to look back on 20-30 years from now for their own nostalgia? The mining of past content to satiate the appetites of people longing to look back really does create a vacuum.
