Adaptation dread

I'm feeling a fair amount of apprehension about the upcoming movie version of "Because of Winn-Dixie." On the one hand, I adored the book, and am happy for anything that gives it a higher profile. On the other hand, the trailer seems awfully hokey, both girl and dog too cute by half, music and narration suggesting quaintness and quirkiness rather than the emotional truth of the story. I loved the low-key, episodic, bittersweet plot, and worry that they'll have to add artificial crises to make it movie-length and -weight. The one review I've read so far was good, so I'll keep my hopes up; but I'll be sad if the film raises awareness of the book just to turn everyone off to it.
