Percy Jackson and the Olympiansis returning to Disney+ just in time for the holidays. The acclaimed fantasy franchise began as a book series by author Rick Riordan, set in a world where Greek Gods and legends walk among humanity in the 21st century, with the lead character being a young demigod named Percy, son of Poseidon. It is one of the best-selling young-adult series, having previously been adapted into two poorly-received feature films. After premiering in 2023, the Disney+ series has seen much more success as it sticks closer to the book.
