What they share
Theysit in Action / Adventure / Animation territory. If that's the register that drew you to JoJo's Bizarre Adventure: Phantom Blood, the second film will land in a comparable space — through a different lens.
What One Piece: Romance Dawn Story is
Here's an origin story no one asked for. Luffy, sent out for groceries, botches the task when he gets lost. A young girl named Silk then vows to defend her treasure from pirates. Serves its purpose, I suppose, for those keeping score at home.
