'Dumb Money' brings a smart spin to its David-and-Goliath GameStop story

"Dumb Money" takes full advantage of its David-vs.-Goliath underpinnings to turn a tale of stocks and finance, a la "The Big Short" or "Too Big to Fail," into a crowd-pleasing underdog story. Paul Dano heads a sprawling cast as the guy leading the rebels with pitchforks on behalf of GameStop, resulting in a film that's smart and satisfying enough to earn every dollar it makes.
