“Sight” is billed as the “incredible true story” of Dr. Ming Wang, with the Nashville-based man selling himself as a leader in the field of eye care. The production aims to make a hero out of Wang, with co-writer/director Andrew Hyatt (“The Blind,” “Paul, Apostle of Christ”) telling the story of the subject’s difficult upbringing in China, and his eventual struggles in America, working his way into medical dominance with a focus on helping the blind to see. The essentials of Wang’s journey are fascinating, as it certainly appears he’s lived through so much, remaining true to his integrity and quest to help others. Hyatt isn’t particularly committed to raw experiences and finely tuned dramatic escalation, going the usual faith-based cinema route with harsh melodrama and tedious speechifying. “Sight” (which was shot three years ago) has a real tale about perseverance to offer, but Hyatt’s in the hagiography business here.
