I think RJ is better suited for his own trilogy

"Johnson has revealed that, after he’s finished with his work on Lionsgate’s Knives Out, his focus will shift 100% toward working on the first of his three Star Wars projects. He’s already got plenty of ideas on the table so far, and it seems like he’ll have his story planned out well before he shoots a single frame of his first movie"

 

Nope. Solo would’ve done just as poorly even had The Last Jedi been praised as the greatest film of all time. It was released at an awful time of the year (literally three weeks after the biggest film of the year came out), had poor marketing, and was not something the casual fans would be into, or at least not as much as they’d be interested in say, a Kenobi movie. But this isn’t relevant to the discussion at hand, we’re talking about Rian being suited to make his own trilogy of films.

Again, TLJ did very well not just in theaters but on home video as well, which is a pretty important detail you failed to address. If the majority disliked the movie when they saw it in theaters, they wouldn’t waste the money to physically own a movie they despise. It was praised by most critics and like @DailyPlunge pointed out: scientific-based sources, such as CinemaScore, showed most audiences liking it and lower audience scores from Rotten Tomatoes and Metacritic have been proven to be unreliable. Just because it’s seemingly popular to hate on TLJ on the internet, it doesn’t mean that the physical majority dislikes it. Watch the Episode 9 Panel from Star Wars Celebration this year and you’ll hear the crowd cheering at the mention of Rian Johnson’s name. I also saw a ton of people dressed up as characters from TLJ alone when I went to Celebration that Saturday: Holdo, Rose, Snoke, Ben Swolo, old man Luke, and even a Porg to name a few!

Like I said in my last post, Rian’s first venture into Star Wars was a financial and critical success. What I didn’t mention was that The Last Jedi had the cleanest production of any of the Disney-era Star Wars films. No major leaks beforehand, no shifts in writers/directors, not having to rush to get it done, no major rewrites or reshoots, and the cast seemed to enjoy working with Johnson, even if they didn’t disagree with some of his choices. Sure, the release date was pushed back, but that’s because they wanted to have a bigger gap between it and Rogue One. (Why Disney was okay with this, but then decided to put their foot down and not push back Solo for the same reason, I do not know...) Rian’s clearly a reliable director to work with, one who has already made a well-recieved saga film, so it’s no wonder why Lucasfilm is cool putting the reins in his hands. This isn’t even including reasons why he’s a good fit from a writing/story perspective, but I’ve already mentioned why he’s a good fit for that in one of my other posts here, so I won’t repeat myself lol.

 

As soon as I finish up with this job I'm working on, I'm starting my work on the manufacture of a time machine.

 

If you look at Lucasfilm's track record since Disney purchased the IP I would expect a lot of big name directors would be reluctant to get involved. They've already fired or displaced four directors for five films. JJ and RJ are the only two that haven't had a ton of problems. Rian Johnson is constantly harassed online simply for making a film most people liked. Some Star Wars fans need to relax. It's impossible for one director to make a film that pleases 100% of people. Marvel has even had some films that weren't super great, but no one hounded the directors.

 

That’s a good point: the mostly troubled productions, as well as the potential to get constantly harassed online, would be a major turnoff for people who would otherwise be up for working with LFL. There are just some fans are too emotionally invested to the point that if Lucasfilm makes one film that they don’t like, they consider it sacrilege to their fandom. Fortunately, most of TLJ’s critics are more reasonable that this. As for Marvel, I’d say that people are less emotionally invested in the series itself and are more invested in the characters themselves. Not to mention, that Marvel tends to make more “crowd-pleasing” films which isn’t what Star Wars has ever stood for, except for The Force Awakens to an extent.
