Let's talk about cannibalism, shall we? Tonight's installment of The Walking Dead, "Strangers", concludes with a gruesome revelation: the survivors of last week's raid on Terminus are munching merrily away on a bit of fire-roasted human thigh—all before the eyes of the thigh's former owner, Bob (Lawrence Gilliard, Jr.). Well then! That's one way to establish irrefutable villainy. But while "No Sanctuary" conspired to portray Terminus mastermind Gareth (Andrew J. West) as an irresistibly charismatic pretty-boy in the register of, say, Andrew Scott's Moriarty, "Strangers" tries a little too hard to demonstrate his bona fides as a worthy season-wide threat.
