Personally, it's my favourite anime/manga with Berserk and 20th Century Boys. The things I like the most are, by far, the characters and their developments, new island = new adventures, the humor is also nice though sometimes it gets kind of too..... I dunno, Japanese-ish. It's weird to say it like that, but sometimes I just don't get the joke

. It's a funny manga nonetheless. Err, what more.... One Piece has Going Merry, and Dr Hiluluk, probably the saddest scenes in shounen (for me).
Characters I really like (examples): Kizaru/Luffy/Usopp/Sanji/Franky, etc. If you like badass characters, One piece has many of them, if you like funny/stupid-ish characters, like me, there are plenty of them too. That's pretty obvious since it has +700 chapters.
Also, if you want an unbiased review, try Googling instead of asking here.
xD and how does my posts counts lol? I've been here for a long time and its pretty sad you seem serious and insulted by what I said. Calm your tits down there and take a deep breath lol . I didn't say the series itself is waste of life I said to read 700+ manga from the beginning is a waste of your life lol. It's even worse if you watche the anime xD not something you start with from the beginning but you act like. 10 years old kid that have nothing better to do other than watch one piece and cry like a baby when someone say something about It seriously go get a life because that's just sad xD
You're arguably one of the worst members on the forum.
why make ur life a shit by watching shitpiece?712 chapters and still no clue where is onepiece,just wow.i think most people will die before they can see it's end,considering it's still in it's midway ,due to less time in life.or maybe it can go on forever like pokemon,until the author .....anyways i won't suggest u to waste ur life's precious time on this piece of shit.
You're retarded.... but still better than Soulkiller.
