I don't know. I can't actually decide if Peru is on to something. According to Boxofficemojo.com's 100 top grossing movies of all time adjusted for inflation at least 16 are from this decade. That is more than a decade's fair share if your tracking at least the last nine decades. But, a movie from this decade doesn't show up until number 29, and that is Shrek 2.

This of course assumes that box office is a proper measure of a movie's event status.
