This is a type of article that makes me crazy:
With an unbroken string of hits stretching from 1995's "Toy Story" to this summer's "Wall-E," you'd think Pixar had story development down to a science.
Not even close ...
What is Variety talking about?
Story has never been a stroll in the park. Story has always been difficult, like trying to bottle lightning ... or thread fifty needles at a dead run. And sure, writer David Cohen is setting up a rhetorical straw man here, but that doesn't make the straw man any less silly.
There are six different plots; all else is embroidery.
It's the quality of the needlework that matters, and in animated films, the sewing and stitching mostly goes on until three weeks prior to release. But this isn't anything exclusive to Pixar, or anything new. It goes on at every studio, all the time, all the way back to Snow White, The Three Little Pigs and Steamboat Willie.
Even the films that turn out bad are tough to concoct.
If there was some kind of science to it, movies would be made in germ-free laboratories by guys with microscopes and Bunsen burners.
