"This archive-rich bio is a candid sit-down with a national treasure."
— David Rooney, Hollywood Reporter
"Not only an eye-opening story about old Hollywood but a testament to the vitality and integrity of an artist who is not showing any signs of slowing down."
— Randy Myers, San Jose Mercury News
"Coming away from 'Just a Girl,' it's impossible not to be convinced that Moreno is the rare screen legend who found a way to stick the Hollywood landing."

"'Rita Moreno' serves as a powerful cultural artifact that will educate future generations of Latinos about a pioneer who survived and conquered a field unwelcoming of her."
— Carlos Aguilar, TheWrap
"Riera mercifully doesn't wallow in West Side Story, and instead shares Moreno's power as an activist and an EGOT-winning performer who continues to break barriers as an 87-year-old..."
— Sheri Flanders, Chicago Reader
"Director Mariem Pérez Riera wisely resists the urge to romanticize Moreno's struggles and thus flatten her life story into an unequivocal triumph, though she certainly came out on top."
