Few would expect the new Showtime docu-series “Oliver Stone’s Untold History of the United States” to win kudos from the Right.

Turns out even mainstream critics are trashing Stone’s latest far-left propaganda.

Take TV Guide, which published a scathing critique of the series debuting at 8 p.m. tomorrow. Veteran TV critic Matt Roush pulls no punches in his assessment:

Oliver Stone’s anti-imperialist screed, which extends from World War II to the conflicts in Afghanistan and Iraq, could have been a provocatively contrarian study of U.S.  foreign, military, and nuclear policy. To bad it’s such lousy TV, delivered in such a droning one-sided lecture in 10 weekly sermons, with cheesy use of archival footage and movie clips (including Mr. Smith Goes to Washington) in the opening chapters.
