I've seen it. I watched some episodes with my Grandma and it was embarassing at times, to be honest, because of the character of the series. It was painful to watch, the formula got very old very fast. It was so cheesy it hurt. I felt Usagi should have more dignity, though I liked her good heart, she was just way too naive and blundered too much,. I really liked her romantic destiny with Mamoru though. I absolutely disliked Seyia in the final season.
Though, in the final season the animation improved so much!
I wished the lines were better. The R season was possibly my favourite one as it dealt with the future. But other than that...had it had a different formula and more developed characters it would have been better. Still..as I say I found the Usagi-Mamoru romantic background story very lovely and consistent and that's the only thing that saved it for me. The rest was rather annoying, especially the cheesy delivery lines about justice, I cringed EVERY time, lol. Later on I liked Yuuichirou, Rei was one of the better characters possibly. I always wanted to see Artemis in human form, though.
I thought the remake was just to update some things like floppy disks to cds? Well no matter, I don't think I have any interest in it any more, much as I liked the romance as it had a lot of heart but I just wouldn't be able to go through the same cringeworthy elements I found in it. I wouldn't call i bad: it had a pretty consistent storyline, it's just not something I would watch again and perhaps it's because I"m not big on magical grls anime fighting monsters in the same way all the time, much as it had an underlying consistency. The highlights were the "boss" fights, but they were very few and far between, obviously.
