One could be forgiven for being skeptical that a Hercules movie starring Dwayne "The Rock" Johnson and directed by Brett "Rush Hour Trilogy" Ratner might have a brain in its head, but it actually does. We're not talking Snowpiercer levels of intelligence, but it's far less aggressively stupid than, say, Transformers: Age of Extinction, or Renny Harlin's recent megaflop The Legend of Hercules.
