Worst Level Design in the game- the Choir room

[Reportin']

I gotta say I liked the Choir very much. Granted, it's not my favourite level in the game (that'd be Cistern Entrance), but it's really different because it's so unexpectedly huge and open.
Sneaking along the walls and through the red haze was really exciting; I actually got lost and panicked when I heard the monster(s ?) approach. And the part where you jump onto that collapsed column was pretty neat as well.
