by James Christopher Monger Composer David Julyan (Insomnia, Memento) infuses director Neil Marshall's caving expedition thriller with taut passages of brooding paranoia and wistful odes to lives lost among the nocturnal beasts that were their prey. Bookended by a wistful theme that channels both the wistful ache of Angelo Badalamenti and the elegiac thoughtfulness of Michael Kamen, Julyan understands tension, dynamics, and minimalist dread like a true professor of the paranormal.
