Oh man I need to watch the original anime! Know a good place I can watch it actually? I literally LOVE fmab haha. And would love to check that one out.
Also.. I'd say to you, and look, I'm sort of picky about these things, as we all are...watch the first half, then switch to Manga. Or just read the Manga from beginning.
I got into one piece without knowing ANYTHING about it so I'm super lucky and grateful.
It's got its flaws, but it's sort of apart of the style. It feels very stream of conscious and home brewed. I absolutely love it to death.
It helps that I started it during a pretty rough patch so it's like a comforting thing for me.
I think ultimately, it's worth it, and the length shouldn't be a barrier. It's just more content and I love the story. It's endearing. OK enough proselytizing. Lol
