Am also one of the ones that really liked it, how it felt and the kind of perspective it gave on our main character.
It's definitely not a instance you can just rush through, unless maybe you read a guide.

I spent two attempts just scouting the area and to realize that the red-line border goes all the way around, that there's something else you need to do to find the way out.
On the third attempt I finally noticed the magitec reaper and what to do to get it working, though ended up with little time left (like 5min at the end) cause I spent a lot of time just being lost and not knowing what to do.
Though I can see how this experience can be very frustrating or irritating for players that just want to move on and don't have patience for this kind of storytelling.
