there was an attempt at rewatching finished series here before right?
but it was organized as a stream marathon?
the idea of rewatching old series isn't bad, but if having everyone online at the same time, to watch it together on a stream, is hard to organize (different timezones, different free days during the week, etc)
the rewatch could still be done, not as a "watch together" event, but by setting a range of episodes to watch over a week, and then discussing them in the clubhouse
i'm thinking the clubhouse forum would be more fit to talk about finished series, than ongoing ones (since there is already the anime forum, and there isn't a big difference in the discussions here and there)
