“This year’s GlobeDocs festival inevitably includes documentaries that look into the darkness of subjects such as racism (“Attica,” “Free Renty: Lanier v. Harvard,” “Who We Are: A Chronicle of Racism in America”), environmental doom (“Becoming Cousteau”), the plight of refugees (“Flee”), sexism (“Jagged”), and COVID-19 (“The First Wave). But it also shares stories that bring smiles (”No Straight Lines: The Rise of Queer Comics,” “Paper & Glue”) and hope (“The Rescue”).” – Peter Keough, Boston Globe
