The
Sailor Moon and
Bishoujo Senshi Sailor Moon nodes already exist to cover the
TV series quite well, but, for clarification, the original
Japanese character names were single-word (Sailormoon, Sailormars, etc.), while the dubbed verion (and, really, any Americanization) separates the words into Sailor Moon, etc. Although this may not strike you as a big deal, certain
Anime purists get offended by such
things and refuse to recognize "Sailormoon" by any other formatting. Yes, I think this is silly, too.
Of course, anyone who won't accept that the character can be called Sailor Moon in addition to the series will obviously hate the English dub.
