‘Spencer’ shows off Kristen Stewart in a ‘fable’ about Diana’s break from the Royals

Kristen Stewart's fierce, attention-grabbing work as Princess Diana really ought to be viewed independently of "Spencer," described as "a fable from a true tragedy" that presents a pivotal weekend in Princess Diana's split from the Royal Family. That is, it's possible to admire the performance and still come away feeling director Pablo Larrain's fictionalized movie doesn't significantly add to a story many of us already know in exhaustive detail.
