Yeah you should! I can say for sure that if you like watching Naruto/Bleach/Inuyasha/Shaman King type of animes, you'll find One Piece acceptable/good if not better. Alot of people did not watch One Piece as the animation is slightly different from nomal and kinda have a kiddish feel about it. But if you can look beyond that, it's actually pretty lighthearted anime with lots of adventure and suspense. I managed to persuade one of my friends to watch it even though he really did not want to. His verdict : Addictive, Funny. He watched like 100+ episodes within a few days.
