Sam Wothington should stick to being blue!
Whoever wrote the script needs shooting. If Perseus said "I will do it as a man" one more time I was ready to throw things at the screen. Perseus had all the emotional depth of a coaster and don't even get me on to Zeus and Hades and the whole thing they had going on with the gods. If they wanted to make a movie about the working class hero overcoming the aristocracy then they should have made one, not butchered Greek myth and ruined a perfectly good story. They should have just let Perseus whine at the Kraken and it would have died of boredom.
The only decent character was Io, all the others were 2D and had kill me tattooed on their foreheads - lucky they were wearing read shirts really.
I'll take the Ray Harryhausen version any time, and I know that was a butchering of myth too, but at least it was a good one!
