TLJ was actually the best Star Wars movie. It explored the philosophical concepts that every action has a consequence, and that decisions are neither good nor bad in and of themselves. There is always a gray area in everything.
The rich slave-owners building weapons for both sides are amazing parables to how capitalism and war-profiteering have separated classes in America. And making a mistake we regret--like the one second Luke questioned Kylo's loyalties, pushing him further towards the Dark Side--is an abstract we can all relate to. Luke isn't perfect, he's human. Kylo killing Snoke, his mentor, because he believed he and Rey could surpass him ties in with that; Kylo feels betrayed by father figures, so he kills them because he thinks it'll be freeing.
There were some epic scenes, too. Holdo's sacrifice. Yoda's appearance. Snoke's death. Luke brushing his shoulder off after the whole army unloads its cannons on his projection. I've never gone "OH SHIT" as much in any Star Wars film.
If you didn't like it, then have no fear. The incessant, whiny, nerd outrage over how exploratory the last film was didn't go unnoticed. Your wish for them to go back to the boring way Star Wars always was looks to be fulfilled. We'll just focus on the same family, pretending they're the only ones who are special, while recycling the tired, played-out idealism of good vs. evil. Hell, it's been 39 years since Episode 5 and you're still using the same final boss.
