I watched this film recently. I started watching it rather half-heartedly as I was doing something else. The film did not grip me very much and it was over a week later when I felt like returning to it, to finish it off. The story is set in Paris' underground catacombs. Some kind of party event is going on down there illegally and a group of friends decide to explore the catacombs on there own. One member of the group is an American who has only just arrived in Paris.
Much of the film is focused on this one girl as she runs through dark tunnels screaming. It's not particularly original or interesting. Neither is it scary. I didn't like this film very much and felt it was a chore to sit through the whole thing.
