Sweet, but with an underlying sharpness and an earth-toned edge
Some on this board have compared Bottle Shock unfavorably to Sideways; I felt exactly the opposite about the two movies. I felt zero sympathy/empathy with Miles and Jack of Sideways, who seemed so incredibly self-indulgent and selfish that it was like trying to relate to someone who enjoyed hitting himself over the head with a hammer "'cause it feels so good when I stop."
I found all the major characters of Bottle Shock -- with the exception of the H'wood Stock Beautiful Young Chick Who Is Here To Be Young 'n' Beautiful -- to have depth and motivation. I cared about Jim, who put everything into a dream that was in danger of going under, and was being swamped by his fears. I cared about Bo, who didn't want to grow up but found a reason to. I cared about Steven, who lived as a permanent outsider in a world he both loved and wanted to challenge. I cared about Gustavo, whose dream paralleled Jim's but whose circumstances didn't, who provided a beautiful foil to Bo. I was delighted by what the film had to say about paradigms and how easily they can become defining forces that fail to accommodate the human spirit.
I'd suggest that the film is just too low-key for most American audiences, who really need some serious electroshocks wired into the screen or their seats before they can say "I've been to the MOVIES!"
