A movie about manufactured consensus would be a vital public service. But "Merchants of Doubt" isn't quite that movie.

...largely preaches to the left-leaning choir with plenty of hissable sound bites and a generally glib tone that undercuts an otherwise understandable sense of righteous indignation.

Aside from an eye-opening investigation of useless and harmful flame repellents pumped into furniture, it sticks to climate change without broadening its scope to other examples of corporate spinning, which must be plentiful.

A criminally underseen documentary.
