"Eragon 2" was cancelled primarily due to the poor critical and commercial reception of the original 2006 film. Despite being based on a popular book series by Christopher Paolini, the movie failed to resonate with audiences and critics alike, leading to disappointing box office performance. Additionally, the rights to the film adaptation reverted to Paolini, and he expressed a desire for a more faithful adaptation. As a result, plans for a sequel were ultimately abandoned, and the franchise has remained dormant since then.

"Eragon," based on the book by Christopher Paolini, is generally considered appropriate for a 12-year-old. It features themes of adventure, friendship, and heroism, with some fantasy violence, including battles and mythical creatures. While it has moments of suspense and intensity, it lacks graphic content or strong language. Parents may want to watch it with their child to discuss any themes or scenes that arise. Overall, it is suitable for a middle-grade audience.

Yes, Disney+ is developing a series adaptation of "Eragon." Announced in late 2021, the series aims to bring Christopher Paolini's beloved fantasy novel to a new audience. The project is still in the early stages, with updates on casting and production expected in the future. The show seeks to explore the rich world of Alagaësia and its characters more deeply than the 2006 film adaptation did. Fans of the book series are hopeful for a more faithful and expansive retelling.
