Not the first among Young Hollywood and, sadly, it certainly will not be the last.

My only comment is that these younger celebrities should a). realize and embrace the good fortune that they've been given - not squander it by leading destructive lifestyles
                                                                                              b). realize that through this good fortune they've become role models to kids and use their celebrity to impart positive values.

Instead, when you think about the legacy of people like River Phoenix and now Cory Monteith (among others), it likely will focus more on the tragic (and unnecessary) circumstances surrounding their deaths.
