I never really paticipated in r/anime ones but wouldn’t hurt to try here. Why not go with Steins Gate or Vivy Flourite Eye’s Song?

I always liked reading along with the /r/anime rewatches, but never got around to really actively participate in them, partly due to lack of time and partly due to different timezones meaning that my comments would come pretty late to the discussion. Also a lot of commenters wrote these really long and elaborate texts, it was honestly almost intimidating.

That being said, this is a different, still much smaller community, and the bar for visibility is lower. I think it would work with an adapted format, like one parent post per rewatch with toplevel comments per episode. The default post sorting on Lemmy takes into account comment activity, so such posts wouldn’t drop off the “front page” too quickly and not clutter the community either.

There was some discussion about doing airing show discussions in that format, but the counter argument was avoiding spoilers for people who are not caught up. But for rewatches, I don’t see that being so much of an issue. In fact, keeping all spoilers for one show in a single post could even be an advantage.
