Fantasy TV shows often base themselves on prior work, whether it be from novels, movies, video games, or even comics and graphic novels. This is because a lot of fantasy shows have a huge world with a lot of lore, so it's just more practical to bring an already existing universe to life rather than try to craft a new one (although this has still been done).

Summer camp season is almost here, and Netflix is about to make the journey to Camp Half-Blood a lot easier. Beginning June 15, both Percy Jackson & the Olympians: The Lightning Thief and Percy Jackson: Sea of Monsters will be available to stream on the platform, giving fans a chance to revisit one of the most imaginative fantasy worlds of the 2010s. The Percy Jackson movies have always occupied a somewhat unusual place in fantasy fandom. Readers of Rick Riordan's beloved novels have spent years debating the movies' changes to the source material, while the recent Disney+ adaptation has introduced a new generation of viewers to the son of Poseidon and his fellow demigods with a more faithful take on the books.
