‘Philly D.A.’: TV Review | Sundance 2021 Daniel Fienberg Philly D.A. It’s the most common question whenever an outsider — be it Ross Perot or Bernie Sanders or Donald Trump — runs for a position of power in an entrenched political system: Having big ideas or exciting the electorate is one thing, but when you challenge the political orthodoxy, how do you actually govern if you happen to win? This is the backdrop of Ted Passon, Yoni Brook and Nicole Salazar’s eight-part Independent Lens docuseries Philly D.A., which is premiering its first two hours as part of the virtual Sundance Film Festival and will launch on PBS later this year. Those first two episodes mark an extraordinarily promising start for the series, which boasts impressive access to Larry Krasner’s Philadelphia district attorney’s office and a nuanced approach that works hard to give this specific situation universal ripples.
