"Wrath of the Titans" is Greek mythology for dummies, but give credit where credit is due. It's mindless entertainment with a cast and crew that knows what their selling -- a 3-D fantasy flick that's big on brawn, but not a lot of brain. Why else would heavyweights like Liam Neeson and Ralph Fiennes sign up for the sequel to 2010's "Clash of the Titans" if not to play brothers Zeus, lord of the sky, and Hades, lord of the underworld, to the hilt? Which they do, of course.

Interview: 'Titans' co-star looks to 'film gods'

Sam Worthington reprises his role as Perseus, where we find him 10 years after having survived his first encounter with the Underworld in Medusa's lair. Now, a single father, he wants to live a quiet life as a fisherman and forget the past. His tranquility is tested when a three-headed fire-breathing Chimera threatens his village and his son. Half-human, half-god Perseus has no choice but to take on the monster. But that's only a glimpse of what's to come.

Deep in Tartarus, the lowest region of the world, the imprisoned Titans are growing restless as is their banished leader, Kronos, who was overthrown for being a bad guy by his sons Zeus, Hades and Poseidon (Danny Huston). Now Hades and Perseus's brother, Ares (Edgar Ramirez) have made a deal with the Devil -- Kronos, that is. They'll capture Zeus and channel his power to Kronos so that he can rise from the ashes and take over the world.

Sidekicks show up to help out: Agenor (Toby Kebbell, who could easily be mistaken for Russell Brand), the goofy son of Poseidon who has been jailed for being a thief by Queen Adromeda (Rosamund Pike). They join Perseus who has now left the village and is on a quest to rescue his father before the evildoers suck the life out of him.

Hephaestus (Bill Nighy), the god of technology, is more Bill Nye the Science Guy than Bill Gates. He's built the labyrinth that leads to Tartarus and he has a map to prove it.

On his way to save his father (which Worthington as Perseus is forced to say over and over again, "I must save my father." Yes, we understand that's your quest), there's plenty of opportunity for the filmmakers to have him meet some of the wickedest creatures this side of the Isle of Kail. It is the Isle of Kail where Hephaestus and his fierce guards, the Cyclops, make their woodland home. The 30-foot monsters are the first hurdle Perseus and his gang encounter, and it's just one of the great adventures in this film as one of the not-so-jolly giants toss Perseus around like a toy soldier.

Director Jonathan Liebesman has a field day taking moviegoers on this CGI filled quest of mythical creatures and huge battle scenes. If he doesn't wow you with the Minotaur, wait until you get a load of the Makhai -- 8-foot-tall, two-headed, six-armed warriors. Now that's a ninja. And the rising of giant, fiery Kronos is the climactic icing on the cake.

"Wrath of the Titans" has a wooden script that's short on depth, but who needs words when the action is this spellbinding.
