There are two responses I get, without fail, every time I try to get someone new to watch this show. "I don't like the art style," or "I've seen the dub - NO THANKS." I'm guilty of both of these myself. But if there's one thing I need to stress before even getting started on this review, it's that the 4Kids dub is NOT One Piece. For the love of god, PLEASE do not think it is. If you've suffered the misfortune of seeing some of the 4Kids episodes, just erase them from your mind and start fresh. They butchered it, there's really no other way to put it. They cut episodes, changed the dialogue to fit a MUCH younger and apparently far less intelligent audience (almost insultingly so), gave the characters RIDICULOUS voices, and pretty much watered down the entire series. FUNimation has done a much better job so far from what I've seen, but regardless, watching it in its original Japanese form with subtitles is really the way to go.
As for the art style, it's true, it's completely different from almost anything else I've seen. Much more "cartoonish" and maybe not what you'd expect from an anime. Despite that, you end up loving it. I wouldn't even say that you have to "get used to it" because it's not something that detracts from the rest of the series in any way. It didn't even take me two episodes before I was thoroughly enjoying it and seeing it as a fresh, new style, exciting almost and unlike anything I'd experienced before. Now, some 300+ episodes later, I can't remember ever NOT liking it, or even why I would have. Especially now with One Piece being aired in high definition, the art is crisp, clean, colorful - VERY sharp and wonderful to look at.
Now that we've got those two points out of the way...
One Piece is actually one of the best shows I've ever seen, anime or otherwise. The plot is pretty basic at first. Monkey D. Luffy has just set out on his own to find the legendary treasure 'one piece' and become Pirate King, and he's looking for a crew to sail with him. You'll find yourself falling in love with each and every new member as Luffy finds them. They're all extremely well developed, with interesting backgrounds and unique, fun personalities. They form one very quirky crew that's always discovering new adventures and somehow getting themselves into trouble as they strive to achieve their dreams. Each main story arc introduces new minor characters as well, and they're just as much fun and easy to fall in love with as the Straw Hat crew. Not one character is left out or feels like they're there for no reason. Everyone has a purpose and adds to the storyline, and one of the really cool things about One Piece is that these 'purposes' often resurface at later points in the series. No detail is left untouched, and you'll seriously be amazed by the way Oda threads together plots and characters and blends all their stories perfectly the more the series progresses.
The plot itself, though fairly straightforward at first like I said, quickly evolves into something HUGE. Much of the beginning of the series is dedicated to forming the crew and letting you get to know the characters, though it's definitely never lacking in action, but once they reach the Grand Line, you're swept up in adventure after adventure and following some of the most fantastic story arcs you'll ever watch. The battles and fights are well-paced, with the final boss fight almost always being completely EPIC. But even through the action, One Piece never quite loses it's lighthearted, humorous edge. The episodes are sprinkled with PLENTY of funny moments, never too many and never too few. There's always a wonderful balance of action and humor.
One Piece also has its fair share of heart-wrenching moments, which may take you by surprise! There are some EXTREMELY powerful scenes and episodes that kind of blindside you and leave you wondering when you became quite so emotionally attached to certain characters or other things. I've definitely found myself near tears or actually crying at more than one point. One Piece has it all - amazing characters, the never-ending yet never TOO over-the-top humor, exciting battles, fun adventures, heartbreaking moments with quick to follow touching moments. And underneath everything, there's always the theme of friendship and teamwork, of working to reach your dreams and helping those closest to you achieve theirs, of growing and maturing as a person and discovering the power within yourself to overcome obstacles of any sort, of just BEING THERE for the rest of your crew when they need you - of being NAKAMA.
In a word, One Piece is perfect. And perhaps I'm just biased, being an obviously OBSESSED fan at this point, haha, but what can I say? It's been running for 344 episodes so far and not ONCE have I wondered or hoped that it would start to reach an end. It is, simply put, amazing.
So why should you watch One Piece?
Because you're missing out on one hell of a fantastic show if you don't at least give it a try.
