Watched the entire first season...
and it was surprisingly good. Ok, it's not exactly perfect since many others will still prefer the anime/manga, but it goes to show that we finally get a US american adaptation that respects the source material. The actors were spot on with their roles especially Luffy, Zoro, and Nami, most of the effects, notably the practical effects were superb, and the music fits the atmosphere (not to mention it made a few nods to the music from the anime which I won't spoil to those who haven't seen it yet).
