Yes, Sailor Moon just doesnt translate well the way it is into live series ( and yes, PGSM is horrendous to me ).
It should had to be readapted reimagining lots of the things trying to make them look good in live action. The sailor suits, the transformations, the attacks, even the hair. But If you change everything then it stops being Sailor Moon. Get rid of the talking cats... Imagine how to translate Sailor Moon or Chibi Moon into live action without looking like a cosplay.
I think it should go trough a process like the one Batman experienced with Cristopher Nolan.
