Percy Jackson. Clash of the Titans. I don't know why they hate Medusa so much, that they sliced her head off her shoulders, not once, but twice, in the movies. Now I really pity her. The movies are both about Greek mythology, all about Gods, monsters, not to forget Medusa.
However, Percy Jackson, is he Perseus? But in the movie, he's the son of Poseidon. If it is, wrong fact. Perseus is the son of Zeus. Famous for beheading the head of Gorgon Medusa and rescuing Andromeda from a sea monster.

Storyline: 8.5/10
Visual Efx: 7.8/10
Sound Efx: 7/10
Overall, I will give it a 4.2/5. Not really "Wow", but able to sweep you off your feet. The length of the movie was perfect, there were some funny moments, and of course thrilling, fighting scenes, crazy 3D models and effects.
If I'm able to recall correctly, this is the only English movie I watched in my entire life, without a kissing scene.
And this movie, is not really for kids, watch Percy instead, blame it on the witches, they look gross.
