It was a weird story about 2 brothers fighting a battle on Earth. Nothing spectecular... not as a SF movie, not as an action hero movie. Just Nathalie Portman who saved the movie with her cute face.
But I'm not a comic fan, to me these heroes seem 80% silly.
Those characters are taken from actual mythology......
They're inspired by actual mythology. Based on if you want. I wouldn't say they're "taken" from that mythology. Either way, that doesn't affect the inherent silliness.
