After finishing this 200+ series (I'm counting Na-i-sho inbetween) I'm sincerely baffled at the idea that this series is not talked more about, in particular by moonies (I. E. afictionados of Bishoujo Senshi Sailor Moon) like myself. Who the hell cares of out-of-time, unnecessary crap like crystal or eternal when you literally have two of the directors who made the 90's superheroics animated masterpiece making the same thing, like the title of this review suggests, with witches instead of superheroines and a more stringent focus on the problems children could face during their lifetime so as to not feel like a cheap, uninspired copycat (Wedding Peach I'm looking at you)? And it's not that the directors don't make copious amount of references to Bishoujo Senshi Sailor Moon, they do (the ending of Na-i-sho, I. E. the true ending of the series, feels like a big homage to the R season of that series), so again if you're a moonie you're perfectly at home. I'm also glad nobody ever thought of remaking/rebooting/whatever this series. Watch this thing and forget Crystal and Eternal ever happened to begin with.
P. S. It's also recommended as an introduction to the wonderful world of Tokusatsus, if this series does not convince you extremely well to watch them nothing ever will period.
