The problem I'm having with the event as it's been announced so far is that, essentially, if zombies aren't your cup of tea, you're out of luck. That imaginative spark and diversity that has made Horror Nights so special to me is slowly disappearing. The Walking Dead has always been about the relationships between the characters and their personal struggles, which made it translate so poorly last year in my opinion. When you strip away the drama, it's just a bland zombie faux-horror.
Here's hoping they pull something interesting out of the bag for the other four or five houses, rather than more film or television IPs.....
