I haven’t read them but based on what we know of them i think George Lucas sequel treatments sucked.

Everyone online is like zomg why didn’t Disney make his sequels.

Whills and Midichlorians and Darth Maul as the big bad are terrible.

The actual trilogy Lucasfilm made under Disney ownership is probably not as bad. But also is disjointed because they wanted to avoid prequel like worldbuilding and politics. And it was a bit of an overcorrection. They really should have shown where the resistance and first order came from, how Kylo Ren came to be and who Snoke was and why Luke failed. And i don’t mean the answers Rise of Skywalker gave.
