How can anyone suggest getting rid of the final trilogy (7, 8, 9) and keep the first (1, 2, 3) with a straight face?
1-2-3, even if not top cinematic masterpieces, were actually part of the Skywalker arc, culminating in the redemption of Vader with the help of his son (kind of a reflection / repetition of his younger self), and the consequent final fall* of the symbolic archenemy of the series, at the hands of the redeemed Vader & Son (in a mutual effort of theirs.)
* see what I did there?
7-8-9 went ahead and canceled the achievement of Vader & Son when the archenemy got returned "somehow". It introduced a bunch of heroes who were rather flat and practically patchy remix copies of the original ones, and tried to sell mostly the same Skywalker story again with some added sequelitis, and with, well, strangely (badly) paced, rather disjointed movies which couldn't decide whether the enemy was a menace or a piece of slapstick comedy.
At least that is how those who suggest getting rid of the final trilogy but keeping the first one seem to see it (with a straight face), as far as I can tell based on what I read here and there over the past few years. (Note that most of these people do like, or even love Rogue One, the Mandalorian, and some other bits which respect the original, so it's not really the IP owner they have an issue with, after all, but the specific creative decisions behind 7-8-9.)
