It's kind of hard to be burnt out on 'Star Wars' because Star Wars can be so many different things. Like, are you seriously burnt out on unrelated side-stories like The Mandalorian or are you just burnt out on the 'good rebels vs. evil empire' meat-and-potatoes of the franchise?However I'd definitely say that I'm burnt out on the mainline films, and that happened even before TRoS came out.
For me that stemmed from a few things:
1) The Sequel Trilogy doing its absolute best to negate the Original Trilogy. In hindsight the entire thing just seemed like an exercise in Disney trying to make their Star Wars the 'definitive' Star Wars, what with killing all the major OT characters, shoehorning the whole 'Skywalker Saga' thing, and canonically making the Empire vs. Rebellion fight mostly meaningless
2) The openly-sexist, racist, etc side of the fanbase who thinks Kathleen Kennedy is the devil and Rian Johnson the anti-Christ, alongside making my dislike of the films a harder position to take, is just disgusting overall. It's hard watching these films and trying to form an actual opinion on them when you know that there's a whole bunch of assholes waiting in the wings that will use those opinions in a motte-and-bailey-styled argument to enforce their own shitty views.
3) Being directly called, or implied to be, an 'idiot who can't understand films' by the other side of the fanbase simply because I didn't 100% love The Last Jedi got old after a while. Sometimes the fanbase, especially on here, can make it seem like you can't dislike anything about that film lest you be inundated with gif spam, direct jabs, and unhelpful, and quite frankly insulting 'insinuations' that you're part of the aforementioned racist, sexist cabal from point 2
So, yeah. I'm burnt out on the mainline Star Wars stuff because dealing with it means dealing with corporate cynicism, insults, sexists and racists, and an endless culture war that seemingly won't end until humanity collectively forgets about The Last Jedi (i.e. when the sun engulfs the Earth). However I'll still dabble in the other stuff if it looks good. I'm one of the five people in the UK who didn't pirate The Mandalorian so I'm looking forward to that for sure, and the new Lego game (despite being connected to the Skywalker Saga directly) is something I'll be picking up day one
