I don't care too much for zombie stories, notwithstanding the fact that I think I wrote one a few months ago without meaning to, but I don't shun them either. I haven't liked all the zombie stories on PP, but I liked this one. I think it was well-written and the story points all worked perfectly -- going into the mine to escape (don't run up the stairs!), members of the party disappearing, Obi-Wan sacrificing himself for the greater good, and then Johnny going ape-poopie at the end.
I think you need to know a little history to really comprehend the background of this story -- because of the accents and the reading (in a positive way), I think I missed some exposition. Or maybe I didn't.
The reading was excellent, though I think keeping track of the accents and the different tones of voice was a little too much. Once it was just Johnny, Hardfall, Edwin, and Thin Rob, it was a little easier, but still.
The coda felt a little empty to me, as my own codas (codae?) often do. Like, okay, Johnny tried to kill zombies, now let's show that he survived. I don't know. Not as chilling as if we'd just been left with Johnny swinging his pickaxe.
Not my favorite kind of story. Not a 100% perfect reading. But both were good enough to create a great episode of PP.
