'Stephen Curry: Underrated' scores in charting his arc from overlooked to all-star

Unlike most biographical documentaries, "Stephen Curry: Underrated" benefits from having two very distinct windows in mind, both buttressing its underlying point: Curry as a barely recruited, under-sized high school prospect, before merging as a college star at Davidson; and his most recent title with the Golden State Warriors. Either would be good enough, but put together, "Underrated" shoots and scores.
