That seems like more of a significant deviation in ethos.... Yeah, it's not a shot by shot remake, obviously
Kal-El gets told by his space dad that humanity has a basic capacity for good and eventual greatness, so he should wield his awesome gifts for their benefit both because it's the right thing to do, and to be an inspiration in hopes of bringing out their own best qualities. Clark contextualizes this in terms of his small-town American values of honesty, justice and hard work.
Hercules gets told by his sky dad to do vaguely-defined heroic things so that he can go back to living in the nice place. Hercules doesn't really have values, just non-descript niceness.
It's also remarkably similar to Rocky.King Snarf said:they're remarkably similar.
The two flavours don't exactly go together.
