I think this arc could have benefited from cutting a few stories and putting in others.
Things we did not need, in the long run:
1) Hercules/Meg storyline of 513
2) James and David
3) Ruby Slippers
Cut those and give us flashbacks of Zeus/Hades’ story and maybe Zeus decision to bring back Hook wouldn’t feel so tacked on at the last second.
