Awesome Art: A constant throughout the trilogy is the stunning 2D animation and gorgeous art direction, which is greatly influenced by medieval Irish artwork and goes hand in hand with the Celtic Mythology-inspired stories.
Fanon Welding: While the connection between the three films is not explicitly confirmed, fans widely accept that they take place in the same world. It helps that beyond the shared use of folklore and setting, there are a few nods between the three that help give credence to this fanon, such as Aisling's cameo in Song of the Sea, and the Eye of Crom from The Secret of Kells appearing as one of Robyn's items in Wolfwalkers.
Friendly Fandoms: Fans of the Disney Animated Canon have quickly embraced the trilogy, viewing the films as worthy Spiritual Successors to Disney's 2D animated films. It helps that Disney and Cartoon Saloon are on very good terms, with Disney getting Cartoon Saloon on board to do a short for Star Wars: Visions.
