Ford, Fisher and Hamill are just used as mere tokens to score nostalgia points with the older fans. They are only there to be auxiliary servants to the new main characters, in particular "Anything you can do, I can do better, I can do anything better than you" Rey.
Ford was just there for the paycheck, and Hamill has made no secret of his disdain for the way his character was abused. And most of the new characters are neither miracle actors nor are they given time to shine (I'm looking at you, poor Captain Plasma). The prequels have "Woody" Hayden, but they also have Christopher Lee and Samuel L. Jackson as well as the aforementioned McGregor and Neeson who tried their best with the underwhelming script. Sure, there is a lot of wooden acting and silly dialogs in the prequels; but the same can be said about the new movies, as hundreds of angry YT commentators will eagerly tell you.
And there are plenty of silly CGI characters in the sequels as well.
As mentioned by others: I don't like the prequels, but the sequels somehow manage to make them look better in comparison. And the prequels have no blatant intention to "woke" me up and sledge hammer some weird "The Force is Female" ideology into me.
Even when Ford, Fisher and Hamill were just brought in/came back for nostalgia/money, they left the other actors behind (not only in comparison with Episodes I-III, but also in Episodes VII-IX). Or in the translated and slightly modified words of Highlander: "Es kann nur diese drei geben"
I mean, wasn't Hamill gesture, when the troops of the new order shooted at him (or rather his hologram), iconic? That was as cool as it gets!
However, I must confess that Christopher Lee and Samuel L. Jackson did a good job too. But I can't find "wooden" acting in one of the main characters in the sequels (only an annoying one in the person of Adam Driver, when he was showing a deviant behavior like a little child after Rey escaped - that was so embarrassing and Darth Vader must have rotated in its grave for shame).
As for silly CGI characters: Jar Jar Binks is voted in many rankings as one of the most annoying characters in the film history ever, mostly on place No 1. A "glory/credit" none of the CGI characters in the sequels has reached so far afaik (= if I did not oversee a ranking).
Regarding "Awakening" and "The Force is Female": These are story related points and I already wrote that I'm entirely with you here (Although some may say that the "unsullied conception of the force" as in the prequels is as weird as the new ideologies)
