While I love the 90’s anime and would defend it to the end.. the Dream arc is superior. Is some of the filler in SS good? Yeah. The double date episode for Minako is one of the best fillers in the franchise! Do I like Fish Eye’s redemption episode? Yes. Other than that, though? It’s a big fat no. Literally 80% of it is useless time wasting fluff. I wouldn’t mind it if it was fluff that acted as development for the main cast but it was literally just VoTD after VoTD. And even then, with so much filler, they decide to combine Jupiter and Venus’ power up episode into one? Make it make sense.
Eternal suffers from the opposite problem where there’s too much development stuffed into a very small amount of time ..but at least it’s pretty exciting (though flawed.) I’d rather take that than hours upon hours of nothing.
I would say the Nehelenia arc of Stars was really well done, though. I think the finale of that arc was better and more emotional than Eternal’s/ the manga’s ending to that arc. With all the Senshi joining hands together to make her see the error of her ways? One of the only times in the 90’s anime that all the Senshi truly feel like a united team.
