I finally got around to finishing Dirty Pair Flash -- I see it took me about 3 weeks to get through the last 5 episodes, which shows how little it engaged me. The final miniseries, despite having themed titles like the first two story arcs, is pure standalones like the original series, but not very good. The main thing that distinguishes Flash, aside from its mediocrity, is that it's closer to the level of raciness, cheesecake, and occasional brief nudity (perhaps a factor in why they called it Flash) that I would've expected from something called Dirty Pair, unlike the original series, which was relatively tame in that regard (aside from a split-second glimpse of bare breasts in one episode and more substantial nudity in the first hourlong OVA special). There were times when I thought Rica Matsumoto (best known as the original Pokemon lead) did a pretty good job as Kei, though both Kei and Yuri were played even more broadly than the originals.
I also recently finished watching the 1994 series Magic Knight Rayearth on Crunchyroll, which I kind of stumbled across and decided on a whim to check out. The descriptions were a bit misleading, as the streamers carrying it give it a mature rating for nudity, but that's just for brief pseudo-nude transformation sequences seen only in the main titles and the season premieres, and it's actually fairly young-skewing. It's a magical-girl isekai series about three schoolgirls who get transported to a fantasy world to become the destined Magic Knights who will save it, along with the, err, giant robots (or guardian spirits that manifest as giant robots) that they acquire toward the end of the first season. It seems like a hodgepodge of pretty standard formulas at first, but then takes a subversive, dark twist at the climax of season 1, revealing some things that provoke a lot of guilt, soul-searching, and moral debates among the characters in season 2, touching on similar themes to Ursula LeGuin's iconic short story "The Ones Who Walk Away from Omelas." It wasn't brilliant, and I found season 2 way too slow-paced with some silly new antagonists, but it had its appeal and I came to be somewhat fond of the three heroines (once I got used to the character designs, which are huge-eyed even by anime standards). Apparently there's a remake premiering in October, and if Crunchyroll carries it, I'll probably check it out.
