Far be it from me to cast aspersions on someone who looks at a life like Shirley Chisholm's and has to choose just enough for a two-hour biopic. But this Netflix film, produced by Regina King and written and directed by John Ridley (whose Oscar-winning "12 Years a Slave" was phenomenal), is a bit lackluster. I don't think it uses the best cross-section of an amazing life, with just the Wikipedia entry alone presenting so much possible material for a biopic.
Regina King is excellent in the title role and the movie is well-intentioned but ultimately lacking in what made her so memorable, focusing solely on her 1972 presidential run with nothing about her work on the ERA or even how she first made it to Congress. The script feels like it takes her quotations and builds a movie around them; you can almost see the pullquote on the screen. Her famous tagline "unbought and unbossed" went unmentioned and unexplored in the entire movie, aside from one sign in the background of a scene. I'd still recommend watching this serviceable film, but keep your expectations in check.
