Fast Review on One Piece season 1:
Great Characters (Protagonists and villains). Nami, Zoro, Sanji, Usop are well written deep characters and are awesome. Luffy is "sometimes" hilarious" but is a baka often. Captain Buggy with its awesome integrate/disintegrate parts power and funny crew can't be anywhere near bad. Arlong and his crew made this season quite interesting, just like Blitzkrieg and his crew. + Dat mysterious swordsman from the Grand Line.
Grey marines-pirates alignment is really interesting. Some great marine captains and admirals (like Smoker) in this series.
Great settings and plot: Pirates in a magical-fantastic world with lots of strange stuff and powers seeking their interesting goals and there is ordinary people and marines (corrupted or not). Fictional Geography: Grand Line, the other line, Calm belt etc. Fights around the Cooking ship was cool and that arc introduced so many interesting stuff. Arlong Park arc was quite emotional and beautiful just like that old dragon arc.
Good music and OK drawing effort.
Nuff said.
