If I’m not mistaken I think this community may have been created in response to its loss, but it hasn’t managed to get as much activity for whatever reason. Prior to the Lemmy.film instance going away, its version of this community had around five thousand subscribers.

That is correct, but the first community was created was created during the peak of Lemmy users post Reddit exodus, we are now much less on Lemmy as a whole. !moviesandtv@lemm.ee is still the most active movie community in the whole of Lemmy.

The media restriction might play a role, but I don't remember that many videos upload from the previous version. What was there though, is the discussion threads that we are discussing here. I opened a discussion on them this morning but got that thread removed (see below). That's a bit concerning to be honest.
