Learning about a Bayou romance from a generation ago, a pair of thirtysomething New York professionals uncover something about themselves in “The Photograph” (2020). Stylishly filmed, scored and acted, it’s like an African-American version of a Richard Gere film – but better, because Richard Gere isn’t in it. Instead, Issa Rae and LaKeith Stanfield are the leads atop a strong cast that checks all the romance-flick boxes – sassy girlfriend, wacky married couple, eager co-worker, gracious boss, etc. Yet, thanks to the story within the story and its long, slow (but not too slow) unwinding, this formula seems more elegant than usual.
