This topic is a few months old, but I felt like sharing....
I've seen the entire English dub (including the movies) except for maybe 2 or 3 episodes from SuperS.
As for the original, I have seen all of Classic through S, the first 3 SuperS episodes, all of Stars, all 3 movies and all the specials. So basically the only part of the subs I haven't seen is SuperS minus 3 episodes.
I have seen all of PGSM including Act 0, Special Act, and Make Up! Bishoujo Senshi Sailor Moon. Oh, and the Hina special and Tuxedo Mask special. And also a handful of the special interviews and such, but I have not seen all of Kirari Super Live.
As for the manga, I own and have read every volume of the English release. I have read the Sailor V translations that actually used scanlations of the manga. I guess the only thing I haven't completely read is the Parallel Sailor Moon.
I have seen quite a few of the musicals (I will shorten the titles to make it easier), and not all of them were subbed though. I have seen Dark Kingdom, Super, SuperS, SuperS K, Stars K, Eien Densetsu K (the senshuuraku by the way), Shin Densetsu Kourin, Kaguya Shima, Last Dracul, Transylvania, Transylvania K, Death Vulcan, Black Lady K, Ai no Sanctuary, Mugen, Ryusei Densetsu, Kakyuu-ouhi, and Shin Kaguya Shima. I've also seen most of Eien Densetsu, Kaguya Shima K, and Black Lady. I have seen most of the guide videos, omakes, fan kanshas, and such (but I couldn't possibly remember the ones I haven't seen).
