The Village Voice mentions the images in the opening credits as one of the highlights of the film:
Ensemble Therapy: John Carpenter Returns With The Ward (Village Voice)
By Nick Pinkerton Wednesday, Jul 6, 2011
"...The Ward keeps its claws in a viewer, though it never wholly attains the promise of its opening credits. Beautiful and atmospheric representatives of a lost art, the credits themselves show images of madness, including woodcuts and antique lobotomy photos, on shattering panes of glass whose shards float across the screen in slow motion."
