What exactly don't you like about the show? What episode are you on?
At first my problem was that Luffy seemed too powerful, then they revealed that water is a problem and swords/knives are a problem and then Kuro cut him up pretty bad as well, so that fixed it. Dude is not invincible.
Then a bit later it didn't seem like the show is using all the potential it has. The universe allows for almost any kind of a story you'd want to tell, but the show kept going for "There are bad guys who should be beaten up." But then, right after I had that thought, there was the single episode story about the dude stuck in a chest and some very depressing backstory on Zoro after that. Again, that fixed it. .
The show keeps fixing everything I could possibly have a problem with. Currently the only "problem" I have left is that I don't like Usopp very much, but considering what the show has done so far I fully expect to love him soon enough.
