Tag is the genre where the camera chases you; the biopic is the genre where the camera reveres you. Put them together and you get the unholy modern hybrid—Wikipedia's "in popular culture" section staged with a budget—where a real person's life is reenacted with enough creative license to dodge a lawsuit. The pairing is less a partnership than a spectrum: from the energetic shallow to the prestige deep, both still just people pretending on film.
