Just a pet peeve of mine but this sort of thing really bothers me. It is a big complex game book that serves as both an adventure and a campaign sourcebook. No one who hasn't run the thing can effectively "review" it as either of those things. The best they can do is summarize it and tell you if they thought it had some cool ideas in it, or not.
For some reason, posting "reviews" of adventures that you haven't actually fully read, much less played, is standard practice for a lot of RPG sites & Youtubers. It's really weird. With an adventure like this, ideally, yes, you'd play it before reviewing but realistically that takes like a year so I get it. But at least read the whole book before reviewing it, as you would read any other book before reviewing that.
