I've followed this series for going on 15 years and it never fails to amaze me. From the characters to the world building, the details are everything here. Until almost 500 episodes in, I honestly forgot about the One Piece, because there is so much more going on. The emotional impact of each saga, and the naturally feel good vibe of this series can probably cure depression (I know it cured mine).
At first glance, I like many others, skipped over this series because of the animation and overall goofiness that seemed to engulf it. I couldn't have made a bigger mistake. Don't be fooled, just like the real world, this world shows a coloful fun facade, but there is a much darker reality that lies underneath. The world is a very cruel and unfair place, but that can't deter you from achieving your dream and exploring all it has to offer.
The main protagonist Monkey D. Luffy, embodies the human spirit as much as any character in fiction, and just like his rubber ability, he always bends but never breaks. His fiery passion and indomitable spirit to become "King of the Pirates" inspires those around him, and his fun loving, free spirited personality and compassion for his crew make him an excellent leader.
The crew itself are full of different personalities and I almost guarantee that you'll relate to at least one of them. Each bringing their own strengths to the crew. As a fan of the original Dragon Ball, I loved the teamwork aspect and sadly, it's something that didn't carry over as well to DBZ, but was somewhat redeemed in Super. By which I mean, there was a point where Goku and Vegeta vastly surpassed everyone else. Whereas in One Piece, Luffy is the Goku of this series, but no one survives in this world alone and strength comes in all different forms, not just raw power. The strongest crew will find the One Piece, not the strongest person.
Eiichiro Oda and his team have been producing chapter after chapter almost every week for over 22 years. The love and detail he puts into everything is noteworthy, and the anime should receive recognition for the voice acting and excellent score, despite how some people feel about the animation and pacing. It's still better than most.
Whether you decide to read the manga, watch the anime or both, take your time and enjoy one of the greatest adventure series ever made.
