I mean, none of them are particularly great movies so the bar isn't really that high. My take is I think the whole new trilogy suffers from is that they don't seem to really know what story they want to tell and that clear lack of planning shows in its execution. So as a consequence, it ends up with a lot of interesting ideas in places and I think that much of the original trilogy characters/nostalgia are used as a crutch to get/keep people invested in this series. As a precursor, I'll also say that I think Solo and Rogue One are good movies (better than the new trilogy ones) but also boring as they really make no effort to explore the rich Star Wars universe and continue to stay centered around the original trilogy. It's probably my biggest disappointment with everything Disney has done with Star Wars to date.
Force Awakens' only real fault is that it's pretty much the same as New Hope with Han, Chewy, and Leia as crutches. It's a serviceable film with interesting enough characters even if the premise is just pretty blah. But we've got a story with new characters, a couple villains, and Rey/Finn being force sensitive folks (as my long understanding is only force users can use light sabers - pretty consistent in what I have seen but never read any books, just movies and games) means more Jedi training / future films.
Last Jedi largely ends up discarding much of the set up from the previous film and then really doesn't offer much back other than Kylo is now in charge, which is a slight problem in a trilogy. I think a lot of the problems here really stem from the overly huge cast of people and the desire to then use them as central parts of the plot. Snoke's quick death undercuts his legitimacy as a villain in rewatches of Awakens as he never really shows why anyone takes him seriously. Sure, Rise shows that he's just a stooge for Palpatine but that's not known here and had he not died so pathetically, could have been far more interesting. Or was he just the first powerful force user to appear and everyone circled around him? Poe never really has any character growth regarding his brash, shoot from the hip decision making (he just gets shot by Leia and I guess realizes what an ass he's been?). Finn and Rose get sidelined on an unnecessarily long B plot that also gets rid of Phasma in a disappointing way and puts the Resistance in a tough spot (which is another failure of Poe's). Honestly, I get why Holdo plays her cards close as she's not sure how they're tracking them but you'd think she would have entrusted Poe's replacement in command (a demotion that could have helped him grow) and the others she trusted around her - or perhaps that's a problem with the Resistance that could have been highlighted. Also disappointing for Finn as they never explore his force use (per my lightsaber understanding).
Rise is just a mess and a lot of it is down to what they're handed (but I would be intrigued to hear what your view on an awesome ending is) and how they finish things. Why do we need Palpatine as I actually liked Rey's parents being nobodies - it makes the force feel more mysterious rather than heritage and actually makes her calling herself Rey Skywalker at the end even more powerful. Why is Kylo leading the First Order not sufficient enough for a bad guy? They could still be looking for the Sith homeworld but trying to find a way to weaken the dark side to return balance to the force (given the diminished light side). The navigation module battle plot makes zero sense and honestly the sudden amassing of forces is comically silly - where did all these people and resources come from? Force revive/heal clearly exists but it's silly that a renounced Sith can suddenly make use of what is a clearly powerful power (ignoring how little training Rey really had and that all the previous Jedi had not come to her when she healed him). I don't think there's a lot of debate to be had here.
As I said, there are a lot of interesting ideas in there but it's such a mess but in different ways from the prequels.
