For me personally, two years ago, Sailor Moon was dead and buried. I mean, I had all my related things packed into neat little storage boxes but I couldn't bear to part with them.
Watching PGSM for the first time... was so horrifying. I remember my eyes being glazed over the whole time cuz I couldn't believe someone had really put this together. It was act 11, for anyone who cares to know.
Today, my Sailor Moon posters continue to hang on the wall where I put them (back up) a year and a half ago. I still love [THE HAPPY PLACE] and hang around even though PGSM is done and over. I still love waiting for the newest pics at Three Lights and well, I continue to build my PGSM fansite.
So, yeah, I'd say PGSM has impacted me. It's turned me into toku as I've become a fan of other shows (Faiz, some Blade, some Shibuya, etc). I know PGSM has made fans of people who previously didn't care for Sailor Moon. A lot of guys, actually.
Seems like... everyone was skeptical about PGSM but as they grew into it, they came to love it. I think it's rekindled something for a lot of us. I mean, ten years ago, I was 12. So, yeah, between then and now, a lot's happened but I can still say, hey! I like Sailor Moon! You can't say that about most things in life. It's been perpetuated and I agree with whoever said that the feeling now is akin to when the anime and manga ended in its loss and finality.
