Hey don't knock the dance show thing... it is part of HHN's long history of entertainment offerings on both coasts, it isn't something new to the event. A lot of people do actually enjoy having shows to see, especially since they might be too scared to go through the mazes.
Besides, this show might even be "monster"/horror themed. Orlando did the same thing with their Death Drums street show in 2011- zombie version, pop tron-esque version, & a sexed up rock version. The rock version was the only version of the show to watch, but it was still great. This being in the Castle Theatre means it will have sets/effects, similar to what they offer in Vegas.
