In general, I'd call it roughly 4 hours of unique content. Many themes are repeated, and perhaps some parts are longer than they need to be, but I loved every second of it because it's always either clever, funny, or interesting the whole way through. It's also broken out into like 20 parts, so there's stopping points roughly every 15 minutes, and thus doesn't feel too daunting to get through (at least to me)

It is granular, yes. But it is presented in a very orderly fashion full of perspective and done in a really entertaining manner! I hardly felt the time passing until my stomach growled xD

I watched it at 2x speed, so it cut it down to 2, which is much more reasonable. The pace of the video is fairly slow, so 2x speed is perfect for it. I do think the video is worth the watch though. 4h? Idk. Definitely 2 though.

It is worth it. I was also skeptical, though if you play it on shorter 30' sessions, feels like an opinionated documentary. There are slow parts though by the end, but I'm still glad I checked and the author is an authority in theme parks.

It doesn't feel repetitive, no.

She's goes into great depth and her conclusions near the end don't really land without the context of the full video. I watched it at 1.5x speed and missed nothing.

For me, I clicked on it to see what it was about. I have never watched one of her videos before. I enjoyed the 30 minutes I watched but then I saw how long it was still to go and noped out. I'm sure it's still good but I don't have time for that.
