It's not only a franchise reboot, but it's a reboot that isn't hampered and deviated by the trappings of today's bullshit policies of Japanese TV stations that ain't giving manga-based anime a fair shot at faithfulness to the source material... hence why it's aired online-only.
Through this method, moonies like myself are finally being treated to an adaptation that is undisputedly faithful to the manga, which means it's MUCH faster paced, Usagi's days as a clumsy ditz are short-lived, the monster-of-the-day formula is gone, the costume details on the Sailors are more accurate to the manga, and by far, each episode plays out exactly like the chapters in the manga. The only real difference is the modern technology updates, which were a given by the director way before production.
So yeah, if you read the manga, you'll love it. If you haven't, I advise you do so now so you'll know what to expect. Keep in mind the episodes are aired bi-weekly on Hulu, Crunchyroll, Neon Alley, and the main source,
