It is always told that Hercules was the lighter series compared to Xena.
But - let's take a closer look at Hercules' fate: He loses his wife and family. This alone is, say, very hard to bear. Then he is regularly haunted by Hera. And in Season 5 his best friend Iolaus dies too (and one could add that Morrigan leaves him all of a sudden). Oh, and I forgot Serena....
Why did Hercules never break down? Had he not had enough reason to end like Callisto?
Was it his "half-godness" taht gave him a stronger mind than normal humans have got?
What do You think?
