Personally, I'm eager for the One Piece Remake to come out because that's when I'll start watching this very popular series, to be honest. I never got around to watching the Toei Animation anime for the same reason you mentioned, that it's veeeeeery long and even boring at the beginning. Imagine watching hundreds and hundreds of episodes to get to the "interesting point" of the story and then watching more than a thousand episodes to stay "up to date". It's crazy, really.
That's precisely why I prefer to watch the remake. And I support the idea of doing this more often with other works that need a good remake—I repeat, a GOOD one. For example, a remake of Dragon Ball Z, one of Naruto, one of Bleach, etc. Who knows if this One Piece Remake project will motivate major production companies and studios to continue doing this in the future.
It's okay to dream, right? 😅
