I was interested in this movie because I liked the TV show Young Hercules, and wanted to see where the story began. I was expecting this to roll in the same groove as the show by making these guys kind of like middle-school or high-school students dealing with the world from a youth's standpoint. Being a bit older than the intended audience (26 now), I always wanted these heroes to have a harder edge, to swear if they needed, to kill their enemies. I wanted them to grow up! Afterall they spent their lifetimes fighting monsters and vying with gods, right? They're entitled to adult language and darker attitudes. Well, I was not disappointed by this movie. (It wasn't over the top, of course.) The characters had the same basic personalities - Hercules with a golden heart and always striving to stay on this side of good, Iolaus the wise-cracking con-man, and Jason the take-charge prince about to be king - but being a movie and not a TV show, I think the writers were given more freedom to make these guys true warriors and not the watered down version that a "tween" audience required from the show.
My one problem, which probably barely counts because I study mythology and have a greater passion for it than most people, was there was no mention of Medea in Jason's quest for the Golden Fleece. And the only female cadet was named Yvenna, rather than making the part for Atalanta, the only female Argonaut mentioned in Greek myth. Ok... whatever, right?
Regardless, I still really enjoyed this movie, and would recommend this to any fan of the Hercules: The Legendary Journeys universe! Especially those fans of the Young Hercules world.
