Characters personalitys not right especially Luffy.
Zoros katana bends in the first episode during a fights... Oda seems to have missed what his characters started like. And it's too mushed together with scenes that never happened characters merging when they never met or coming into the show way to early. All seems rushed and scenes of convenience for characters meeting. Missed out the determination of Luffy getting the trust and loyalty of those he has as his crew.
