I'm so excited for this! Sailor Moon had a significant effect on my television upbringing!
I've never read the manga unfortunately, but I always hoped they'd make a version that was more related to it.
I remember having to research everything online about specific characters aswell as other events that went on in the story.
Like the Shitennou, and how the were Darian/Momoru's advisors in the past life, before being corrupted by Metalia.
Speaking of Melatia, the dub kind of confused me with that whole "negaverse" bit. Especially how they carried it into Sailor Moon R.
I remember being like " Wait... didn't Sailor Moon get rid of those guys and the big black evil face in the sky or..."
And just as they did with Endymion's guardians, they did the same with Sailor MiniMoon and her court. Granted it didn't take away much from the quartet, but I was pretty bummed when I found out they were supposed to be Sailor MiniMoon's future guardians through the manga and not the anime.
Another things that annoyed me the most was how Sailor Moon was the only soldier to achieve her eternal form. I would've loved to have seen that!
And I had to read up on information about who Sailor Cosmos was, aswell as other things that I was confused or annoyed about.
That being said, I still appreciated and LOVED the anime. I just hope I can love this version just as much as the original, and I'm happy Takenuchi is finally able to have more control in the development of her brilliant series.
