Am I suppose to be rooting for the humans?

Rating: 2/10 (17 April 2011)

All the humans seem to lack common sense. Most of them spend time angering the God despite witnessing their might countless times. It also seems that they deserve punishment. It actually felt entertaining to watch the humans get punished by the Olympians.
The main character Perseus was also unbearable to watch. He has no redeemable features and spends the rest of the movie screaming at every character in this movie. The only expression I saw on his face was anger and dull surprise. I couldn't find it in myself to root for him.
How can you have a movie of heroes and villains when you feel like rooting for the villains?
