Who is this loser and what is TV Trash?
Isn't it the 2000s version of Star Wars with the same thing hapening to it ironically enough. Shit sequels and prequels (i think the Star Wars prequels are fine but Jar Jar needs to fuckin die).
Not exactly. Star War's "dead period" was from 1986 (when the original Marvel comic ended along with spin-offs for Droids and Ewoks) until 1996 when the toy line was resurrected. While Dark Horse was putting out comics and the Expanded Universe novel series were coming out, the franchise was basically on life support and had very little merchandise support.
Star Wars continued to churning out stuff after Episode 3 ended and the Clone Saga series happened with the cartoon churning out new media. Star Wars hasn't "gone away" sine the 1996 toy revival in terms of merchandise, as it's now one of the "evergreen" franchises that is a staple of toy shelves/merchandise, after being MIA from 1986-1995.
Compared that to Potter, where you have ZERO media of the core series. Just a bunch of fashion dolls for US toy markets (Japan and UK have different toy lines of varying quality that run on and off) and the Lego stuff which only just resumed a couple of years ago after a substantial hiatus. Fantastic Beasts doesn't have dedicated merchandise outside of Lego and the Potter Play which exists in a legal limbo where Rowlings allowed it to be staged/the script published, but refused to give it canonization due to it being a fan work and the controversy over Black Hermoinie.
Potter's chief legacy these days are the movies, which are something of an evergreen product for stores though evergreen box sets don't last these days (see how the James Bond franchise fares in terms of walking into a Walmart or Target and find them on the shelves) and the books, which may or may not be available unless you go to a dedicated book store that stocks them as evergreen selections.
Also, as mentioned, Rowlings keeps the franchise under super tight control so if the lunatic left does renounce it and manage to make the backlash stick, it could create some tension for Rowlings even with her fuck you money. And while Warner Brothers has to bow before Rowlings now, I would not be shocked if there isn't a remake the second she dies done to "restore the franchise" to the lunatic left and basically replace the original eight film series/book series as "the official" version of Harry Potter and the only version you are allowed to like or buy.
