Serenity did NOT cheat on Endymion. Where did you get that part from?! Darien is killed at the beginning of the Stars season. Serena did not do anything with Seiya. So, how did you get to "cheating"?!
Anyways, the show will not be aired again. Naoko took all the anime of Sailor Moon away in order to premote her live action Sailor Moon series. The only part left, is the second half of the SuperS and the Stars series. They would have a better chance of just brining it out onto DVD instead of airing it on the tv.
There are nuidty scenes, and other things that children should not see on prime time tv. Besides, if children see these things- and the parents are not aware, they could get mad and then sue or something. Brining the show to DVD would be easy. At least, easier than airing on tv. Just put a t on the DVD or something.
