It may be an unpopular opinion round these parts, but I agree with GlastoEls – in part.
Lucasfilm’s failure to preserve the OOT is an attempt to erase true warts-and-all classics of film history and replace them with shiny, sanitized, plasticized versions.
Whereas, although the PT are undeniably bad movies, making fanedits of them isn’t a task of the same urgency that preserving the OOT is. I see PT fanedits more as glorified fix-it fanfic of sorts.
