Lady Luck was the icon for Halloween Horror Nights XXI. She was a beautiful and seductive woman, that would morph into her true form of a twisted monster the more chances her prey took. Lady Luck was the first Icon not to have an "Icon house", although Your Luck Has Run Out can be viewed as being her "Icon scarezone". She also played a key role in the back stories to each house, while also making cameo appearances many of them.
As with the past few years the houses were exceptional. The only one I found to be a weak link was The Forsaken. The Forsaken took place on a haunted conquistador ship, and although it was an excellently themed and produced house, all of the scare-actors had glowing green eyes which made it easy to spot them in the dark thus ruining the scare.
Nevermore: The Madness of Poe took you through some of the works of Edgar Allan Poe, with each room focusing on a different story or poem. The Thing took you through the Arctic station from the prequel/ remake movie of the same name. Saws N' Steam: Into the Machine was the only house to ever be based off of a previous scarezone. It took you through a future utopia world called "The Horizon" where those who were no longer worthy of the civilization were harvested to power the city.
H.R. Bloodengutz Presents: Holidays of Horror was the years comedy house and brought you into different horror movies based off of holidays, each room had an introduction from H.R. Bloodengutz himself. On a side note Mr Bloodengutz really hated it when you called him Bludengootz. The In-Between was a 3D house that brought you into the pages of a deranged comic book. Winter's Night: The Haunting of Hawthorn Cemetery was the best house of the year in my opinion. It took you through a cemetery in the dead of winter. The house was even cooled down to 40°F with frost covering many of the set pieces. In Nightingales: Blood Prey guest walked through the trenches of WWI where demon nurses preyed on the wounded and dying. This house is right up there with Winter's Night as best house of the year, the cramped feeling of the trenches and war sound effects really immersed you in the world of the Nightingales.
