Gay rights documentary Stonewall Uprising opened Friday in select cities to mixed reviews.

The film officially premiered in April at the Full Frame Documentary Film Festival in Durham, North Carolina.

Based on the book Stonewall: The Riots That Sparked the Gay Revolution by David Carter, the film digs deep into the gay community's “Rosa Parks moment,” the now-famous three-day riots in June 1969 when gay patrons – many of whom were drag queens – of the Stonewall Inn in New York City fought back against a police raid, refusing to be hauled away in paddy wagons.

But in its review, the Washington Post said: “For a movie about a groundbreaking gay rebellion, Stonewall Uprising plays it much too straight.”

“Historical context, archival image, talking head; lather, rinse, repeat,” reviewer Dan Kois offered.

And D.C. gay weekly Metro Weekly was uninspired as well. It said the film offered “a lot of historical backwash” in awarding it only two stars.

“While Stonewall remains a turning point for the LGBT movement, Stonewall Uprising doesn't represent a turning point for our insights into that fateful weekend,” reviewer Tim Plant wrote.

Variety, however, praised the movie's directors, veteran filmmakers Kate Davis and David Heilbroner, for their “cohesive” and “well-structured” documentary.

And a poster at the Washington Post disagreed with the paper's review, saying: “I saw this film last weekend and found it totally engrossing. … Go see it and be amazed at how far our society has come and how important it is that we continue to fight for our rights and prevent a return to those dark days.”
