Two identical floors of the most boring, repetitive content and enemies. If you want to full clear it on your first playthrough, it’s effectively four floors. Even more because you have to backtrack to get through myriad blocked doorways.
Culminating in a boss fight that is the opposite of the complete snoozefest you just experienced. You’re totally unprepared for a hectic, clusterfuck of a fight, if you’ve never seen it before. An absurd mismatch to the floors leading up to it.
It’s like doing the Twilight Strand and walking into The Maven.
And you only get 1 attempt to boot. You can’t make this shit up!
