At the time?... um, by that time this attraction opened, TWD had been at HHN 4 years in a row (2012-2015) in maze form... and 3 years (2012-2014) of Terror Tram & SZ form.. The only thing it was capitalizing on was a dying show that had already run its course when this attraction opened in 2016.
The problem this attraction had from day 1 was that it was under "show control" rather than "attractions", hence the crappy & random hours. USH wanted to be cheap when it came to the scareactors in it. So rather be open/close with the park it has the random times. Although lately its been continuous as far as being open.
There's a reason why Universal Japan gets all the good stuff (besides the obvious direct connection to everything coming from there). Everyone is all excited over Nintendo which isn't even on the horizon here anytime soon (which is both sad and hilarious). Imagine if USH had spent the money on a well done Resident Evil attraction (walk-through, ride, or even interactive like Japan had).
Not every ride or attraction is supposed to be meant for everyone. That's the problem with the mentality of the world today. "Everyone is a winner!"
