Let's be real, HHN is the only theme park event worthy of being called an event. It's the only one people endlessly speculate on throughout the year, only one with major announcements that generate tons of hype and it's the only event that stops everything theme parks when it comes out. There are podcasts, websites, forums just dedicated to it and only it. Nothing can touch it, so why bother fighting it? If Disney made a scary event in MGM, it would be ripped into shreds. Unfair comparisons would be made and the constant backlash from fans and press because "Disney is making something scary" would be a disaster. Disney was never known for making horror movies, just leave it to the masters.
Also yawwwwn, survey period, do you want to see walking dead return? Just ready for some eventual leaks that are somewhat legitimate, none of that "prop master" garbage
