for me is following the manga from panel to panel, well the first season if they didn't change it and add thinks for me would have been perfect, not having fillers, and things like that, maybe only change the consecutive of what happen to make it more understandable
As far as adapting the manga 1:1 that doesn’t seem to be a problem. The animation is cheap and the character designs are hideous (I’m not a fan of Takeuchi’s artwork Toei did it better in the 90) also its the changes they make from the manga, specifically the first arc that were its biggest crimes. The best stuff in the first arc? The Senshi killing the Shitenou, Venus slaying Beryl with the Moon sword? All gone.
I love how they adapted manga panels 1:1, but am not a fan of 1 chapter - 1 episode approach (some chapters are mostly dialogue and others are mostly battle), so I’m glad Dream arc is going to be adapted into movies
