Surplus of shark films: Social commentary or just for thrills?

Our guests review "47 Meters Down: Uncaged," in which four teenagers dive into sunken ruins that turn out to be hunting ground for great white sharks; "Blinded by the Light," about a Pakistani teen growing up in 1987 England, who finds an emotional outlet through the music of Bruce Springsteen; "Where’d You Go, Bernadette?," about a woman who seems to have it all...and then disappears; "The Amazing Jonathan Documentary," about the final tour of a dying magician.
