I can't express in words of how amazing this movie is. All I have to say is go watch it for yourself.
This review will be broken down into four parts: Music, Animation, Characters and Story.
Music: If you watched the trailers, you know that two tracks of Avril Lavigne would be played in the movie but you won't hear that until the credit rolls. First half was "How You Remind Me" and then "Bad Reputation" played after that. The original soundtrack was brilliant. It was different while at the same time maintaining that One Piece feel we all love; high tension to melancholy themes that played throughout different scenes.
Animation: There was a lot of CGI just like Strong World. The action scenes were animated far better than anything I've ever seen in previous One Piece movies or the anime. The angles and camera movements following every scene was done fluidly.
Characters: The title of the movie is quite self-explanatory. The movie focused on Z, at times even more than the Straw Hat gang. Character Z, also known as Zephyr had such deep story to him and if you love backstories of various characters in One Piece, you'll definitely love Z's. As for our lovable characters, the Straw Hats each got their turns to shine in this movie, however the stronger and prominent fighters such as the Monster Trio(Luffy, Zoro and Sanji) had their own individual opponent to fight. Franky was the next in line after the Monster Trio. Usopp also had good action scenes, but not quite on the same level. Nami and Robin at times were used for fan-service until the climactic battle at the end. Chopper was funnier than ever before, but not entirely important to the story. Brook didn't do a lot in terms of getting into battles, but he had his comedic moments just like Chopper.
Story: This movie as an entirety was built around the Marine lore and back story. This will have it's drawbacks for some though. The story had lots of explanation regarding the principle themes of the Marines and some characters were basically used strictly just for the sole purpose of providing exposition. To fit the plot in a movie length time span, it was surprisingly well done. This was one huge gripes that I had with Oda's previous project, Strong World was a bit of a let down. With Film Z, I feel that he understood what it took to make a movie that retains the breathtaking aura of One Piece series, and he delivered it.
I'd be surprised if this movie doesn't win major awards in Japan, it surely deserves the Best Animated Japanese Film Awards. Perhaps it should even be nominated in Oscar Awards Best Picture because this movie just nailed it.
