My complaint with Jungle P was how friggin' lazy they were when it came to showcasing the villains. The Acinos' side was good, but the Thriller Bark was too empty and boring. They didn't even put Ryuuma or Cindry in it, and it looked like they just ripped the poses straight from the cover of volume 47.
I was thinking: you know the part of We Are when it started flashing the villains (Buggy, Kuro, Don Krieg, Arlong, Alvida, Smoker, and Dragon)? I think it would be neat if they flashed villians from this part of the manga, like Duval, Kuma, Blackbeard, Kizaru, Sentomaru, Sengoku, an' I dunno, maybe Mihawk.
If they're going to keep the two minute length, I hope they eschew the instrumental part of the song, because that would be kind of boring to sit through.
