John Erick Dowdle directs Perdita Weeks, Ben Feldman and François Civil in this found footage shocker set in the catacombs of Paris.
Unlikeable characters, who can only spout their CVs and guessed exposition, survive far, far too long in this weak stew of The Descent, The Da Vinci Code, Flatliners and a lot of ropey old shite. Fittingly it belongs in a sewer.
