My favorite season (call me nostalgic, lol) is the first season. Although Moon Pizza Action (as I call it) will always stay in my heart, I really just love the first season. It's just fun watching Usagi go through becoming a superhero and finding the other Senshi. I loved R also. I actually don't really remember S and SuperS xD, and I also loved Stars. But Usagi being depressed really but a downpour on that season. It was also much, much different than the manga. I loved the Stars manga a lot.
