I'm not sad about this at all. New year, new start. Then we get one movie after the next. Hopefully these films (we don't know if they will be simulcast) can be cut into "episodes" or however they choose and a few months or so afterwards distributed to fans worldwide through their platform of choice.
This will also give Eternal more room to earn money with everyone not so focused on the pandemic. Hopefully and possibly leading into the announcement of the Stars film in 2021/2022 or whenever.
This gives them more than enough time to fix any "errors" between the two Dream movies.
As far as the poor hand, it's all about the money. Toei still owns part of Sailor Moon so I doubt they are going to be too poor with it as long as there is money to be made. Perhaps, unknown to us, there were complications such as budget and time constraints, which caused things to get messy. From a biz standpoint, things can get messy at any time from the slightest thing.
In any case, I'm still excited because I know there is a movie (two) that are made and are waiting to be released in due time.
