I've seen a lot of great animes with great stories and plots but, personally, One Piece is on my top list, by far. I know it has a lot of episodes and that's mainly the reason why people don't want to watch it but, don't let the it's length stop you from watching it. It may seem kind of boring at the start but if you keep watching you'll understand more about One Piece and the next thing you know you can't stop watching it. So, for the people who hasn't watched this anime yet I highly recommend that you watch it.
