The Walking Dead 5.01: "No Sanctuary" (2014) directed by Greg Nicotero
I was pretty geeked about the show by the end of season 4, feeling that it had gotten to a great place of tension and drama. That mostly continues with the start of season 5, which finds the gang trapped in a train car in Terminus, the cannibal city. Though ready to fight their captors as soon as the doors open, they are disabled by a teargas canister and taken to a slaughter room instead. There, a man systematically cracks each person on the back of the head while another slits their throat over a trough. It's brutal and probably purposefully reminiscent of ISIS videos. With the help of a Rambo-ish version of Carol, our main characters manage to escape and leave Terminus burning.
Though is this is all very exciting, I'm not sure I like how they're using the cannibals as compared to the comic series. In the comics, they were just a small group of nuts who would secretly kidnap people for food. They even grab and eat a part of Dale! I actually can't see the TV series going that far. Here, they're more of the stereotypical "small town with the dark secret" thing in the mold of Texas Chain Saw Massacre. I dunno. Maybe I'm just pissed that the group talked Rick out of going back to town to finish off the rest of the cannibals, like they so effectively -- and correctly -- did in the comic.
