Hercules Killed his Wife and 6 Sons
Driven mad by Hera -- or maybe just on a drunken bender -- Hercules killed his Wife and 6 sons, when he recovered from his madness/hangover he undertook the labors he's known for to atone for those deaths.
Seeing no mention of Hera (who messed with his mind/got him crazy drunk), the oracle Pythoness (who he consulted) or King Eurystheus (who assigned the labors) I'm guessing their going to totally leave out that "little" detail that only served as THE ENTIRE BASIS FOR THE 12 LABORS OF HERCULES.
Why can't Hollywood ever take a story that works and make it compelling without dumbing it down, getting it mostly wrong and totally missing the point?
