from a movie perspective it's awful. like half of it is pointless filler (i.e. the whole casino planet part). there are tons of weird little inconsistencies and plot points. character development is all over the place. there are some lines of dialogue that feel like they were written by Tommy Wiseau (the throne room scene with Snoke immediately comes to mind, how the movie starts with a Yo Mamma joke, etc). There are tons of other details (how Luke was handled as a character, how there is no real established villain or conflict, etc), and altogether these add up to a pretty crappy movie.
from a star wars fan perspective, it's even worse. i have long had the belief that star wars fans dont necessarily like the movies as much as they like the potential of the franchise. They like to hear about a planet or see some cool looking character like Boba Fett and wonder about him. The new trilogy does nothing to spark this imagination. there's no real cool new locations, no cool new aliens, etc; there is no sense of a conflict or universe being any bigger than what is presented on the screen.
for all the hate the prequel trilogy gets, the one thing it nails is that sense of scale. you've got politics, a bunch of prominent alien races, expansion on the sith/jedi lore, tons of new planets with their own history & culture, etc. the new movies have none of this, they're just generic blockbuster films with star wars assets plopped in there. if you took out the X Wings and lightsabers and replaced them with something else TLJ could be any other movie, there is nothing "star wars" in those movies besides superficial, surface-level shit.
this hits it all pretty well too
