“The Walking Dead”: “18 Miles Out” episode to air Sunday

As “Walking Dead” fans know, there is much more to this series than zombie attacks.

Sunday’s episode entitled “18 Miles Out” explores in depth the recurring themes of how to survive in an apocalyptic world and how to do so and retain some sense of humanity at the same time.

Whether there is any hope to be had for a life worth living in this walker-filled world is also a question that is dwelled upon.

These subjects come into play as Rick (Andrew Lincoln) and Shane (Jon Bernthal) try to decide how to deal with the outsider rescued from town last week and Hershel’s (Scott Wilson) youngest daughter faces an emotional crisis.

Lincoln and Bernthal, two of the best actors on television right now, deliver stellar performances in this episode, which also includes some pretty intense zombie encounters.
