I too think that caliginous is a reach (at best) in this context. Foggy London-town is caliginous; an underground cavern is caliginous; looking back, the Middle Ages are caliginous.

edit: we might be hard-pressed to come up with a better c-word to fill the bill, but.

catachrestic would have at least been self-referentially humorous. or how about chalcenterous?! :)
