Hercules transformation

There are many changes made in the Hercules movie from the original myths, overall I believe they were made for the better.  This movie could not have been a children's movie if not for these changes.  For example, omitting the murder of his family is probably a good thing, as that does not make for a great child's movie.  Next, Hades is not he real villain in the myths, however is the easiest character to fill that role.  Many children know that the devil rules hell which is equivalent to the underworld and that the devil is evil which makes an easy transition to them interpreting Hades as the devil.  Also in the myths the first labor Hercules faces is not the Hydra, but it makes sense why the film makers changed that.  The Hydra isn't something Hercules can defeat with brute strength because when it is defeated it just comes back twice as strong.  It shows his ability to not only fight but to think and come up with the creative idea of burying the Hydra.  This battle shows off a number of Hercules' skills and that is why it is used as the first labor.
