The best adaptation ever made of an anime, of course, there are bizarre things but there's no way to adapt One Piece without having bizarre things. Kuro, Helmeppo, Koby, Shanks crew, Nami, Mihawk, Usopp are PERFECT.
It's a good opportunity to at least watch the Arlong arc, which is summarized in the live-action in episode 1. That way, you'll know if you'll like it or not.
That's right, to start watching One Piece, you have to take your time. The episodes are very interconnected, so if you watch without paying attention, it might get quite boring.
