Just finished watching it.
I honestly enjoyed reading the (spot-on) spoilers more, a couple of months before release. That seems like a weird thing to say, that a Reddit post was more entertaining than a major Hollywood film with the full financial backing of the mightiest company in the industry, but...
The thing is, when this story was on the page, and I was imagining it all, the general concepts seemed really cool. In practice, what they put on the screen was remarkably less compelling.
That kind of tells me that Rise of Skywalker has a lot of good thoughts on how to make a fun Star Wars movie, but no ability (and perhaps time) to execute those concepts properly.
