If you like movies with graphic killing scenes and plenty of action, I would most definitely recommend this.
All you need to know is that Theseus is a mortal dude with a great body and no fear (of course!) who Zeus seems to like. King Hyperion is all about wiping out the weak and becoming "immortal"/famous and Theseus has to fight him. There's lots of killing and blood and sword fighting. There's the hot chick he is destined to get with and a bunch of gods upstairs fighting over what happens downstairs.
4/5 entertaining, loved the blood.
