Three years ago, a man was found in a cage in a remote cave. The locals claimed he had been alive for 250 years. A team of researchers working for the U.S. Department of Defense let the man out of his cage, where he proceeded to feed on the blood of the team captain. The DoD team was able to kill the man and save the team captain's life. However, the man's bite changed the team captain. What happened afterward precariously balanced the fate of the world. This new series is adapted from Justin Cronin's best-selling trilogy of novels which explored the end of the world in epistolary form. The main science fiction element is the science experiments in Project Noah, which has refined the virus found in that cave through a dozen or so test subjects. Because of the variations in the test subjects and the alterations to the virus, the different test subjects display different traits. If the former team captain is a Nosferatu-esque vampire, the young woman many trials later is closer to a Vampire Diaries vampire. I'm provisionally on board after the pilot. The science experiment has me interested, and everything with grown up Zach Morris and the little girl, Amy, was magic. The stuff on the margins -- the security captain sleeping with the head scientist, grown up Zach Morris's drama with his ex-wife -- felt like it came from a lesser, more formulaic show. Saniyya Sidney is incredible as the little girl, Amy Bellafonte. She is really smart and really emotionally present without being overly precocious. And the pseudo father-daughter chemistry between her and Mark-Paul Gosselaar is terrific.
