Hercules

Sure, it takes a lot of liberties with Greek mythology and Greek history. It's not even totally faithful to the 1997 movie with the same name, to which it's supposed to be a "midquel". But still, "Hercules" is rather educational (there are facts about mythology and history in it, if you only care to look for them) and really funny. It must be one of Disney's most underrated TV shows ever!

It follows the adventures of the young demigod Hercules, who's not only a hero in training (he lives with his trainer Philoctetes), so it's often up to him to stop the plans of his evil uncle Hades, the lord of the Underworld, or to solve other problems. But he also has to go to High School, just like any other teenager, and face typical teenage issues. He's got two best friends, Icarus and Cassandra, but he's often taunted by Adonis, the arrogant prince of Thrace, who considers him "a loser".

The ancient Greek gods, like Zeus, Hera, Ares, Athena, Apollon, Artemis, Demeter, Bacchus, Aphrodite, Poseidon, the Muses and Hermes, all make appearances, and so do many heroes and monsters from Greek mythology. And like other reviewers have said, this show also have an impressive cast list, even for guest roles. So if you can, check it out!
