Naruto the Movie: Legend of the Stone of Gelel
What they share
Theysit in Adventure / Animation / Fantasy territory. If that's the register that drew you to Escaflowne: The Movie, the second film will land in a comparable space — through a different lens.
What Naruto the Movie: Legend of the Stone of Gelel is
Naruto without a leash. While on a simple search-and-rescue, Naruto, Sakura, and Shikamaru are ambushed by Temujin, a knight in search of a powerful artifact. The three ninja are separated, leading Naruto to wonder about Temujin's motives. A nice, self-contained adventure for fans of the series.
