I’ll try to keep this short because most One Piece fans have already watched at least some of OPLA. If you loved it, great! I’m with you. If you hated it, great! Stick with the manga and/or anime.
Seriously, as someone who doesn’t watch the anime on a regular basis due to its slow pacing, I get it. The One Piece manga/anime is created for Japanese boys. One Piece Live-Action is made for a broader audience. It’s also tasked with fitting an entire arc into eight episodes. Entire scenes, characters, and plots had to be cut to make it work. And, I think it does work. It works surprising well. But, yeah, that all depends on someone’s personal opinions about One Piece. So, if you didn’t like the changes or what was cut, I understand why you’re not feeling it.
