"Fulcanelli was determined to perfect an invention which would provide him with the key to eternal life. He was to name it... the Cronos device. 400 years later, one night in 1937, part of the vault in a building collapsed. Among the victims was a man of strange skin, the color of marble in moonlight. His chest mortally pierced, his last words... Suo tempore."

Cronos - 7/10. A man-made-younger-by-weird-scarab-thing licking blood off a bathroom floor to slake his thirst is creepy. And then there's an alabaster man who tries to seek revenge against the man-who-would-also-have-it, who cares. Guillermo always seems to shoot himself in the foot when he reaches too far into fantasy (especially when he's already got a pretty sweet set-up), and the show's no different here. Take the first half, leave the rest.
