I left it absolutely invigorated and optimistic for the franchise. I saw it had some flaws, with one sizeable one being that it should have ignored the cliffhanger in TFA and caught up 6-12 months later*; the OT (and less successfully, the PT) got to handwave a LOT of character development by simply letting life happen offscreen. Still, TLJ took a needlessly derivative setup from TFA and set the stage for a much more interesting Episode Nine than we got, and I utterly disagree that he didn't get or like Star Wars. Shit, Rian Johnson is the only one who was willing to SAY the words "Darth Sidious."

I thought he gave a thoughtful fan's perspective on what Star Wars needs to be to remain relevant, the theme of growing from failure being particularly well done for a big popcorn franchise. The scene with Rose's sister, the Yoda scene, the acting from Adam Driver after the throne room scene? All peak Star Wars IMHO. Then of course TROS came along and was so clumsy and petty in how it blew up Rian Johnson's new directions, and so generally messy, that it didn't even please the people who hated TLJ.

TFA was useful as a palate cleanser for the generation who rejected the PT, and it gave us a compelling new batch of heroes and villains (Snoke honestly being the least interesting as a character), but it didn't really DO much, and its worldbuilding was absolutely retrograde. TLJ was a needed course correction, but Disney not only recoiled from the backlash, but took all the wrong lessons from it even if it did need to affect the direction of Ep9. JJ was, in the end, very wrong for Star Wars, though if TFA was his only one, it might not have been so obvious.

*-Two others being the framing device of the "slow speed chase" and Finn's arc being such a minor step forward . A few tweaks to the technobabble or moving them to Crait earlier and having it be a bit more of a formidable facility could have helped the first one, and having Finn more explicitly trying to save Rey and Poe at the cost of the Resistance might have better highlighted the additional layer of growth RJ was thought he still needed.
