I do get why, at a visceral level, people want to tackle these films in particular, and fanediting is the kind of hobby where if you're doing it properly you need to have some appreciation for the sources you tackle.
But, nonetheless, when I see yet another prequel trilogy edit (with exceptions for things like Frink's Ridiculous series, the Heavy Metal Star Wars series, or the Silent Prequel trilogy, all of which work hard to do something interesting in its own right) I kind of sigh to myself.
Witha similar feeling around the newer films, in part because it feels like many editors rush to release something ASAP after the home release, rather than taking as much time as is necessary for the project to gestate and develop into the best possible version that it can be....
I don't object to people editing what they want to edit, but I find myself wondering what the point is of having dozens of variations on the same material. Oddly enough Blade Runner 2049 seems to be an exception here, in that while there are quite a few projects around it quite a few are fairly inventive, at least in their goals. But maybe that's bias because I am more interested in that film.
To spin my thoughts in a more constructive direction, I think it would be very interesting to have an opt-in challenge for editors over a period of time wherein they take on a new project with the limitation being that it can't be something using a primary source which has already been (or currently is) the subject of an edit.
