"After tackling the Ebola crisis in its first season, Nat Geo’s anthology drama The Hot Zone returns to reexamine the investigation behind 2001’s Anthrax mailings, which killed five people and infected several more," says Saloni Gajjar. "The six-parter offers a cut-and-dried look at the heinous crimes which took place in the weeks following 9/11. But the narrow approach is drawn out and dull, despite captivating performances from lead duo Daniel Dae Kim and Tony Goldwyn. The Hot Zone: Anthrax makes an effort to touch on a monumental incident that usually gets overshadowed in 9/11 coverage, but it still doesn’t offer a lot of new information. This is a linear retelling of the case through the eyes of FBI agent Matthew Ryker (Kim), an amalgamation of the agents who actually investigated the letters. No time is spent fleshing out the lead character beyond his passion for finding the culprit. Dressed only in sharp suits and a perpetual furrowed brow, Kim can only do so much to save a relatively one-note script."
