I've heard from many people that this is a great manga. Where is it at? How long do i have to read before it starts getting decent?
I just finished the Fishmen Arc, and the only things I've seen are a plethora of ridiculous so called "evil-doers". A clown with a silly power, a ship full of horribly drawn feline-esqu pirates, and half human sea creatures that created the most boring Arc I've ever read in a manga. The only arc that started off decent ended in friggin cat pirates, with their leader being the most ridiculous thing I've ever seen with his weapon. I'm a huge fan of Furi Kuri FLCL, and this manga is more outrageously silly in as negative a way as i can possibly mean it.
How long do i have to read before this manga becomes interesting!?!?
Edit - Actually i liked the Chef on the Sea Arc (whatever its called). That was a good story that kept me interested. But it took so much effort to get there....
I liked a lot of those stories retroactively, but personally the arc I fell in love with was the Water 7/Ennies Lobby Arc which is chapter 322 to 430. So, if you're not sure, then I guess you could skip to there and check it out, see if it appeals to you?
I wouldn't approach One Piece as seriously as you seem to be doing. The art is....well I'm not going to say its beautiful or anything. It definitely took a lot to get used to, and I still don't really love the people designs, but the art functions better than most other manga. It's very full, with lots of things happening in the background, and a very creative cast of secondary and one-off characters. One of the best things about One Piece is every arc has a different set of characters that you've never met before, so there are 20 to 30 new people you are suddenly meeting, with a few that reoccur. And the action of the art is always really clear, without sacrificing information and story. It's one of the best paced mangas, where I can honestly say that maybe over 95% of individual chapters are pretty great on their own as well as part of a larger story arc.
The thing to remember about the characters on One Piece is because of there being so many, character complexity is necessarily sacrificed. So most of the characters are pretty simple. That doesn't mean they won't surprise you, as Luffy is generally stupid but has moments of pretty great insight, just that you shouldn't expect super realistic, three dimensional characters.
More than anything, One Piece is just really fun. It's a great manga for being over 700 chapters long with god knows how many volumes and yet it's still really fun to read. That's an achievement. That doesn't mean you'll like it, as One Piece is the most shonen, shonen that ever shonened and I know shonen's are getting a lot of backlash right now. But if you do like it, it will reward you continuously.
