The fights in and of themselves aren’t the main attraction in One Piece. If you go in expecting the same DBZ/Goku formula, you’re going to be disappointed.
A lot of the scenes people are posting only really hit once you’ve followed the characters long enough to know their stories and what they’ve been through. The Enies Lobby arc (with that leopard looking dude) doesn’t really have much impact until you know Nico Robin’s backstory and motivations.
Like I said, read/watch until you finish Arlong Park (which wraps up in episode 44). If you still don’t like One Piece at that point, then drop the series and keep it moving.
