Additionaly, this movie has an odd religious message,... ... ...

... ... ...At any rate, this is a very fitting story for a movie made in today's religious belief climate, I guess. It would have never flown in 1981.

I don't think the film had any point to make about religious beliefs. I think it was an unoriginal and confused mess because it had nothing to say and went with easy choices, even if they didn't make sense.

The producers wanted a nice clear conflict, preferably about freedom, like "300" had. Who is there to rebel against? The Gods!

The hero needs motivation. To restore his kingdom is not cliche enough. How about something easy like Revenge? A god killed his father!!! Briilliant!

The hero needs to be conflicted like all heroes, and also be a superhero. Lets give him god-powers! Doesn't that go against the theme!? We'll have him not use any until it's really badass, so the audience won't care!

Who's the main baddie? Hades. Why? Didn't you see Disney's Hercules? And Zeus is the good guy, despite being a rapist and King of the Gods who are the main problem in the first place.

It's amazing that this film is both:

Way more complicated than the original.
Has even less emotional depth than the admittedly shallow original.
