Yet ANOTHER wretched hive of scum and villainy.
Merry Christmas (or Solstice, or Yule, or whatever mid-winter holiday you happen to celebrate)!
And I do have to admit, fond as I am of many aspects of the sequel trilogy, I do feel like there was only the barest bones of an outline for it, overall, and you can definitely see the lack of a single voice providing the primary story, as compared to the original trilogy or the prequels (which had a very unified story, just incredibly ham-fisted storytelling...)
I do think that Rian Johnson tried to tell a more mature story with TLJ...we didn't have the clear-cut Good vs Evil motif, the good guys did some not-very-good things and we saw a lot more shades of gray on the periphery, which reflects the different era in which the film was created (we are more cynical and jaded as a society than we were in the late 70s). I can see where that turned a lot of people off, because Star Wars is kind of marked by the simple black-and-white morality, although some of the favorite characters (Han Solo!) didn't fit that mold. But I really liked it.
I didn't feel like ROS was undoing stuff from TLJ, so much as saying, "It's not always that simple..." I can't get into specifics without starting to drop spoilers, so I'll leave it at that. And I'm probably more favorably inclined to it simply because I was afraid JJ was going to load us up with another impossibly huge threat that couldn't be justified (like Starkiller Base siphoning energy off a sun, or firing an energy beam that miraculously splits somewhere down the line into multiple beams, and is not just enough to destroy a planet with a single blast, but multiple planets, at the same time...) He has a penchant for doing that, and it never fails to annoy me. But I felt like almost all of the threats in ROS were plausible, and the one or two that took me out of the story were incidental to the plot, not key plot points, so I wasn't constantly reminded of just how implausible they were. So, going into it expecting to be disappointed in that way, and then NOT having it happen, gave me a very positive spin on it. I don't think it's a great movie...but I think it's a good movie.
