As always (and unlike Michael Moore), Greenwald's other rhetorical strategy is to remove his own voice from the mix, avoiding the common outsider- tilting-at-windmills pratfalls of most exposé docs. For every PR-savvy claim to civic responsibility made by CEO Lee Scott, the documentary lines up a wageworker or company officer to refute it with their personal experiences. Viewers may not be surprised to learn of Wal-Mart's horrific track record, but they can't deny Greenwald's airtight advocacy.
