Quoted from HoakyPoaky:
This is pretty well documented.
Fans went to see TFA multiple times, since it was the first SW movie in years. General public caught up in the hype too. Shit I saw it 5 times myself on opening weekend, which I will admit was completely excessive. It wasn't until later when I realized it really wasn't a great movie & the characters were unappealing, but fans were still hyped because well...just wait for Luke in Episode 8!
R1 was a great movie & well supported by fans. Didn't make as much TFA, as characters were unfamiliar to the general public. But it proved that a SW spin-off movie could be successful, if it was done right.
The worm turned for TLJ. Fans obviously revolted, didn't go multiple times like TFA. Bad word of mouth prevented huge box office numbers. The fan resentment only grew worse after the release of the movie. Disney realized they may have a big problem on their hands.
Six months later with that bitter taste still fresh, Solo releases. The story that really didn't need to be told, with a well publicized troubled production & a lousy lead actor filling an iconic role. Fans flat out rejected it & it bombed. Disney sticks head in the sand, blames "too many SW movie releases", scuttles plans for all future spin-offs.
Fast forward to 2019. The hype train for Episode 9 is practically non-existent. Majority of fans don't care about how the story ends, some even plan to boycott Episode 9 completely. Disney just puts head down & wants to get through this. Just move on to next trilogy after a huge upcoming 3 year layoff. Focus on smaller scale SW TV shows in the meantime until they reassess & reboot the properties & studios.
The only thing that can help Episode 9 is a big boost from The Mandalorian TV show, which releases about a month before Episode 9. It should get the fans excited about SW again, because unlike these new movies, this show to catered to the 40 year old fans & looks very promising. That might happen, until fans realize oh yeah, they killed Luke & these movies blow. Yeah sorry but no thanks.
1979......we need to cash in on that star wars thing and create our own cash cow........lets do Black Hole (1979) - hmm that didn't work
1982......that star wars thing is still going strong (Empire 1980).....we need something to compete with Luke now!.......lets do Tron (1982) - IMO superior, but not a cash cow for Disney
2010.......those star wars prequels......they made money......what can we do - Tron Legacy! (still superior IMO, but not a cash cow)
2012........hmmmm lets shoot the farm and do John Carter.....Flop!
2012......screw it - lets just buy George Lucas and star wars!
2018......Dammit we've destroyed our golden goose!
I'm not sure how they could've screwed things up so bad to be honest. It shouldn't have been rocket science. They should have skipped the original characters and story and did old republic or done something new........if only there wasn't something they could've drawn on that fans would be behind......something like 3 decades of top selling stories and books......oh wait
Black Fleet Crisis
Dark Nest Trilogy
The Old Republic
Fate of the Jedi
Darth Bane trilogy
New Jedi Order
xwing rogue squadron
and about any other 500 fantastic books/stories. Guess they couldn't afford it after buying out Lucas???
