Honestly, the disdain among skiffy fans for Avatar is one reason that I lost most interest in fandom a decade or so ago. People for whom any kind of sf/fantasy film or TV show is a momentary entertainment that they a) don't take seriously and b) don't view any differently than a cop show or a movie about fast cars generally seem a lot more hip now to what's worthwhile and what's not. That special investment in the fantastic and particularly in the entertainment franchises that exploit it just throws people's perspective way off.
