When I think about Sailormoon, the first thing that comes to my mind are my friends telling me: "that's a girl's anime!". I don't think that at all. Sure, the main audience are teenage girls, but if we go by that, then the "shounen" animes are just for boys, and that is wrong.
About the anime itself, I loved it mainly because of the great friendship that was built between all the senshi and how they always managed to get out of trouble (with some help from tuxedo kamen xD).
Usagi and Mamoru must have been the first anime couple that I loved from the very beggining
