One Piece is my all time favorite manga. It is easily the best amongst the several long running manga along side it. The world is vast and ever expanding, the characters are surprising and entertaining, even characters the characters that I hate I can't help but like in some ways. That's truly the most amazing thing about it, there are so many characters, each with their very own personality, no duplicates, and even still they are still captivating.
Story wise, I'm always on the edge of my seat. It sucks you in, once I started I couldn't stop, I absolutely needed to know what happened next. And not because the chapters would end in cliffhangers, but because I was pretty sure I knew what was going to happen, and I just needed to see it immediately. Twists and turns leave me not knowing where to go next, but the endless setting has me buckled in for the ride. Truly, this is the only manga I have read that I believe falls into the genre of an 'epic'.
The Dialogue can be hilarious, heartwarming, exhilarating, nerve wracking, mystifying, and heart wrenching... Sometimes all at the same time. Everything said is worthy of quoting. Enough said.
Animation is nothing short of fantastic, the characters jump off the page, all attacks, expressions, and movements make me feel as if I'm getting all of the positive points of watching the anime, whilst reading the manga.
And as I said before, constantly entertaining and enthralling. I'd recommend this to anyone, hands down.
