One Piece Film - Strong World
Yeah okay, that was pretty good. It's certainly not as epic or complex as most of the manga story arcs, but as a relatively stand alone "big deal" movie project, I think it delivers pretty well. It's clear a lot of the movie was conceptualized based on what would be visually exciting, with a lot of cool stuff packed into a 2 hour movie runtime. Instead of developing a more complex multi-layered arc which works for a manga medium, here it's a very clear cut "save the world" setting with a simple objective and a rather basic but visually interesting setting.
One thing I really loved about the movie is how it totally nails the feeling that the movie is set after the Strawhat crew is really established as 300% certified badasses. There's a tone throughout the film that they're super strong, and super confident. There's no sense that they doubt each other or are relatively noob pirates like the earlier parts of the manga. That scene with them marching into the meeting room was soooo perfect. Plus, Luffy looks fucking great in a suit.
Having read about 260 chapters of One Piece in the past week though, I'll say that as a villain Shiki is really quite a let down. It's hard to imagine him being that much of a threat to the group after all the shit they survived in Skypiea, Enies Lobby, and Thriller Bark. I was sort of hoping that towards the end there would be some twists to make it more dangerous, but I guess that wasn't within the scope of the movie.
Still, it was a fun ride with good action and lots of cool "One Piece" scenes. Good comedy, solid action, great posing, and the predictable but awesome transition from silly Luffy to serious badass Luffy. This might not be a particularly strong story emotionally nor is there much of the Oda magic in the narrative, but in terms of tone and execution, it definitely felt like a "movie" as opposed to a TV special or long TV episode.
P.S. Toei's CG ships are godawful. They stick out like a sore thumb and the texturing is really ugly. Ugh. Lol. Also, this movie really shafted Nico Robin. She had almost NOTHING to do aside from some background stuff. Didn't even have a solid action scene to herself. Meh!
Baron Omatsuri vs Strong World comparison
I guess now that I've seen this, I can finally compare it with the only other One Piece movie I was interested in enough to watch - Mamoru Hosoda's movie about Baron Omatsuri. In terms of "One Piece"-ness, I definitely agree that this is much closer to what One Piece represents in the manga, and there are better fights, and more cohesive flavor in terms of fitting into the world of the manga. But artistically in terms of making a beautiful and unique film, Hosoda still wins.
