The production value on this thing is absolutely amazing. Its like walking inside of a Hollywood movie set. There are two separate haunted houses...one with mental patients and car crashes, which is smaller and not quite as interesting. It looks like they're either reusing old ideas or trying new ones out, but it still does a pretty good job of scaring people (based primarily on the reactions on the teenage/college girls within earshot.)
The second has more of a haunted house/gothic theme going, with extremely high decorations and @#$@#$ gargoyles. Yes, there are freaking things with wings flying around on wires that can scare the crap out of you. The main reason this matters is because everything and I mean *EVERYTHING* has to be looked at that it might have a possibility of moving and scaring the crap out of you. The makeup is such that the supposedly dead bodies can easily turn out to be living at any given time. There are also enough hidden doors and tight spaces that it is easy for something to come at you from any angle, but the @#$@#$@ gargoyles add a whole new dimension because you have to look UP in addition to everything else. A lot of the larger monsters were amazing to look at but not scary per se with a few notable exceptions. The final critter does not move much but especially when you look over your shoulder in the mist just as you exit it is extremely impressive.
Oh, and the very last thing that hits you, you will never see coming.
