It took me 10 minutes to drop it, i'm sure.
The animation is still a major factor when it comes to watch anime in my eyes. One piece animation is just weird and awful, i can't get used to it. I've tried 3-4 times and i just can't watch the first episode.
The animation is that way because well the Manga artist has a unique way of drawing, it is not the animators fault. Also look at the gif in my sig and tell me if you like it.
Trust me, the story grows on you so much you'll forget about any animational or charachter design flaws.
I started one piece, and I really liked both Zoro and Luffy, but from the spoiler pics I had seen I was pretty damn sure I would never like "that long nosed guy" but I grew used to him and right now he is one of my Favourites. But even after that guy was introduced, I was absolutely sure there is no way in hell I would like "this guy with weird balloon like hands" but that guy was cool too.
Then came the part where I was like "that skeleton will never be my favourite no matter what" but I was proven wrong once again.
Trust me I used to be choosy about anime quality too, but the story makes up for it and so does the music and humour. I will therefore not suggest manga, stick to the anime, you will get feels like you have never known before.
