After the events of the first film, Perseus has settled in for a humble life as a fisherman with his son. His father, Zeus, approaches him to help fix the walls of Tartarus or risk the escape of the powerful Titan Kronos, but Perseus declines, preferring the simplicity of his life and leaving the gods' work to the gods. Zeus is left needing to ask Hades and Poseidon for help, but with the help of Zeus' son Ares, Hades double-crosses them, kills Poseidon and imprisons Zeus, with the intentions of letting Kronos free. Before dying, Poseidon tells Perseus to recruit his son Agenor, so they can get the god Hephaestus to take them to Tartarus to stop Kronos' escape. With the help of the princess Andromeda, now a slick female warrior, to find a way to Hephaestus. When there, he explains that the only way to defeat Kronos is to combine Zeus' thunderbolt, Poseidon's trident, and Hades' pitchfork into a powerful super-weapon called the Spear of Triam. They arrive at Tartarus, but it's too late: Kronos has been awakened. Zeus apologizes to Hades for banishing him to the underworld and earns his forgiveness, but Ares refuses to acquiesce so easily to his father's apologies. Hades, Perseus, and a weakened Zeus must find a way to team together, defeat Ares, and destroy Kronos before every god is destroyed and the world is left without any deities to watch over it.
Best part of story, including ending:
It takes a lot of established mythology, decimates it, and leaves the nonsensical remains on screen. Nothing in this story makes any sense whatsoever.
Best scene in story:
Bill Nighy is terrific any time he appears in a sci-fi or fantasy film, and his mere presence, ever humorous, is the one shining spot of an otherwise tragic failure.
Opinion about the main character:
Somehow, Perseus is even more bland now than he was in the first film. He's been given longer hair, but less personality, and Worthington still can't generate any charm.
