One piece: Omatsuri danshaku to himitsu no shima

The sixth One Piece film, Baron Omatsuri, and the Secret Island, deviates significantly from the television series in terms of animation, sound design, and character development. I must say this now: if you enjoy One Piece for its combat, go somewhere else. This movie focuses on enhancing the crew's emotional ties, which are highlighted in key storylines, and emphasizes how vital nakamas are to every one of them.

The Mugiwara pirates discover a letter in a bottle promoting Omatsuri Island (Festival Island), a pirate haven, while they are traveling the Grand Line. However, the crew is set up for experiences akin to the Skypiea arc, which are all based on Japanese festival games (goldfish capturing, etc.), when they arrive at the island ready to unwind. While the other members of the crew begin to gradually disintegrate, Luffy, who is always upbeat, is content to play the games. This movie is far more enigmatic and, at times, even disturbing than the television series-especially toward the end when things get desperate. To avoid giving anything away, I'll end the story there.
