I've gone into detail on them in other threads, but to sum them up, the sequel trilogy are thus far even worse than the prequels. Not only do they destroy any sort of internal logic that survived the prequels or were founded by them such as Ma-Rey Sue being as strong as the plot demands or suddenly any ship being capable of decimating a flagship via Light Speed Kamikaze, but characters in The Force Awakens seem to contradict their character in mere minutes apart (eg. Finn not being fine with killing strangers, yet is fine to help the man who killed his best friend and kills his peers who he can relate to without mercy. Rey not seeming to like BB-8, yet refuses to sell it in the next scene, etc.) The prequels at least brought new elements into the franchise and despite sharing some similar plot points to the original trilogy, rather than simply retreading the same plot as past films.
Not only that, but Kathleen Kennedy's SJW agenda is an apparent cancer to the franchise. Not only is the inclusive pandering leading to characters being remembered purely for their race/gender and not for what "character" they have (eg. Rose having no character other than being the token Asian/fat chick/tumblrette), but their attempt at empowering women by depowering men makes the entire situation cringe worthy. The Last Jedi presents all the male characters as either dumb, weak willed or wrong (especially with Luke's character assassination), whilst presenting it's female characters as intelligent, powerful and opinionated, expecting the audience to go along with it despite such obvious straw men not leading to well written female characters.
The sequel movies have some merits, but they're even more few and far between than in the prequels. This is why in a previous thread, I mentioned the notion that I see the prequels to the sequels as I see GT to Super; good ideas and poor execution VS poor ideas and poor execution. Only thing I've liked from the new movies is Kylo Ren's character arc, and even that is just an emo version of the Legends character Darth Caedus. It's still good enough that I'd rate TLJ above Attack of the Clones, but if it weren't for this character arc The Last Jedi would've been the worst Star Wars movie as the majority are heralding it as. I'd still say the movie is minimally better than The Force Awakens due to Finn and Poe being far more consistent characters than they were in their debut and Rey not having quite as many Mary Sue moments, but I'm comparing one turd to another.
The Force Awakens - 2/10
The Last Jedi - 2,5/10
Don't have much hope for Episode IX other than maybe being slightly better than these two dumpster fires.
