If movie director can adapt a 800 pages book in 2 hours movie like Harry Potter they can adapt a manga without problem in 2 x 70 min movies... That the secret of a good adaptation...
And if the movies are huge success on Netflix (what I think) I'm pretty sure they will adapt them somehow in a TV Serie... That could be also ONE reason why the movie are called Eternal and not Crystal. This is basically what happened with DBZ movie "Beerus" and "Freezer" and the creation afterwards of DB Super.
You have no reason to believe that.... wait till I least you see one of the movies before already being negative about them....
The reason why Dragon Ball Super adapt "Beerus" and "Freezer" on the TV anime was because they need to show these arcs for new fans who didn't see the films. After all, these arcs will be important for future arcs.
There won't be a reason to adapt Dream arc again, since it only lack Stars to complete Sailor Moon..
We are all agree anyway that a TV Series would have been better. But the quality would have probably been totally different... If the Netflix deal is successfull maybe it will happen somehow
Honestly, I really doubt this will hapen.
If Sailor Moon is succesful on Netflix, it is more likely they want to create its own version (like Knights of Zodiac for Saint Seiya). They will likely start from Dark Kingdom again.
