As Above/So Below
The high concept: why not set a horror film in the world's largest mass grave — the catacombs beneath Paris, a world of cramped tunnels, unforseen pitfalls, and millions and millions of human skeletons, many of them neatly disassembled and stacked? The motivation isn't terrible, as these things go: academic superslueth trying to realize dead Daddy's dream of locating that alchemical Holy Grail, The Philosopher's Stone. Descending into the kingdom of the dead to find the key to eternal life — good times! There's even a propulsive energy that keeps things going through the exposition-heavy outset. But alas: once our team gets underground, the film turns into an FPS video game, and a poorly built one, at that. A squandered opportunity. 2014.
