This is the kind of thing a sexually frustrated cabin boy might dream up after six months shipwrecked on an all-seawater and manga diet: a power-crazed Japanese piratical fantasy that lands with all the subtlety of a 100-minute guitar solo. The world's buccaneers all turn up to Delta Island for Pirate Fest and a chance to hunt for renowned outlaw Gol D Roger's booty. But they've been hoodwinked: festival MC Buena Festa has teamed up with the grudgeful Douglas Bullet, a peanut-headed, musclebound brute with Michael Bolton hair, to lure them all into a trap to usher in a new pirate era.
What starts off like cosplay Wacky Races soon snowballs into non-stop battle royale. The various pirate crews are a stupendously imaginative carnival, careering into the melee proclaiming their chosen power-move in gairaigo (ie, loanwords). These names have surreal brilliance: Gum-Gum Kong Gun, Zeus Breeze Tempest, Blade of Beauty ... St Exupéry (WTF?). Dialogue is decipherable only by One Piece connoisseurs (not as much of a problem as might appear - this is the 14th film based on what is apparently the all-time bestselling manga series). Characterisation is as profound as a skeleton privateer laughing at his own farts.
Every time you think director Takashi Otsuka has hit a ceiling for either ridiculousness or destructiveness, he effortlessly busts through both. "Go be the strongest somewhere else," yells the masochistic hero Monkey D Luffy (voiced by Mayumi Takana and Colleen Clinkenbeard) after yet another beating by Bullet. The character animation is rough-hewn and spirited, all the better to capture One Piece's scurvy rabble, and contrasts well with the digitally invoked mayhem, like Bullet's purple crystal tsunamis. All the destruction does get a bit wearing, but it seems churlish to complain: this makes Pirates of the Caribbean look like Swallows and Amazons.
... we're asking readers to support open, independent journalism. Reliable, fact-based information and calm, empirical reporting has never been more important. Partisan politics are warping the conversation, getting in the way of public health and global security. At this time of uncertainty, the Guardian is sifting through the noise and chaos in order to give our readers the critical stories and information they need from dozens of our correspondents all over the world.
More people than ever before are reading and supporting our journalism, in more than 180 countries around the world. And this is only possible because we made a different choice: to keep our reporting open for all, regardless of where they live or what they can afford to pay.
We have upheld our editorial independence in the face of the disintegration of traditional media - with social platforms giving rise to misinformation, the seemingly unstoppable rise of big tech and independent voices being squashed by commercial ownership. The Guardian's independence means we can set our own agenda and voice our own opinions. Our journalism is free from commercial and political bias - never influenced by billionaire owners or shareholders. This makes us different. It means we can challenge the powerful without fear and give a voice to those less heard.
None of this would have been attainable without our readers' generosity - your financial support has meant we can keep investigating, disentangling and interrogating. It has protected our independence, which has never been so critical. We are so grateful.
