You are ready to call millions of viewers "obsessed" because of their interest in a drama like this? Instead of passing it off to obsession, why not do a little analysis. If we grant the fact that most TV "news" is actually entertainment, then what's wrong with being entertained? Reality shows are all the rage on TV (or were, I'm not sure), so there isn't much of a mystery as to why Greta is getting the ratings.
Excellent point. Maybe when the Bachelor returns in the fall, this story will be second page news. Sorry, I still find some of this a little obsessive.
