Just finished this; it's only 3 one-hour episodes, self-encapsulated, and very good.
I'd heard In the Flesh called "the thinking man's The Walking Dead," and that's pretty accurate. As much as I like TWD comic, the TV show leaves me cold due to its unrealistic human interactions and nonsensical decision making. This show uses zombies and the zomb-pocalypse as an allegory for... well, any number of othered groups, but most specifically and topically about homosexuality.
