Is this why some people don't like WTWTA?
It's like going to a party and finding yourself surrounded by too many jerks that spoil the fun.
WHERE THE WILD THINGS ARE doesn't provide the comforting escapism from their personal problems people enjoy with most fantasy movies. It antagonizes some viewers because it is so unexpectedly realistic in it's savvy depiction of immature, selfish, violent, paranoid, angry, psychotic, self-pitying, predatory, hypocritical, unconsciously jackassy human beings (of any age) with all of their dysfunctional behavior and whatnot that it is simply off-putting for the masses.
I picture people getting psyched up for a flick about weird-yet-funny monsters and end up feeling almost lectured about their personal flaws and crying. Being a self-confrontational masochist, I embraced it and loved it.
