When a team of explorers ventures into the catacombs that lie beneath the streets of Paris, they uncover the dark secret that lies within this city of the dead.
Not as scary as The Blair Witch Project or as claustrophobic as The Descent, AASB is an admirable Indiana Bones misfire.
Ultimately, despite a few silly moments, this is a pacy and suitably creepy horror enlivened by strong central performances from Weeks and Feldman, though you can't help feeling that the found footage element adds very little and could probably have been dropped.
There are some interestingly contrived moments of claustrophobia and surreal lunacy, but this cliched and slightly hand-me-down script neither scares nor amuses very satisfyingly.
It's derivative and formulaic but John Erick Dowdle's hellbound horror definitely has the "boo!" factor.
