I think it was a fantastic video. Yes it was extremely long, but like someone else said it was broken up into 20 parts, so I could watch it over several days. It was great to be able to see what the experience of Galactic Star Cruiser was really like, now that we cannot experience it for ourselves.
While you are not wrong, that is kind of her thing long form video essays. So I'm socked people are surprised by the length. But I guess not many people on this side of the internet knows her.
YouTube has a feature where it will remember where you were up to on a video if you stop watching before the end.
I used this feature to watch this video over several days. When I felt like I'd watched enough for one sitting, I stopped watching, then later I started watching again from where I left off.
