Unbiased first timer.
Went to Death Row and then to Slaughterhouse, both good. I rate Death Row at 8.5 and Slaughter House at 7. You will have fun at either, especially, from what I observed, if you have a date that screams easily. I doubt that any of these houses will be better than Death Row if for no other reason than you get a good solid hour of fun at Death Row Haunted Prison. It is huge and great atmosphere run by police. Slaughter House about half hour.
Where are the actors???.
Okay, so the animation was great, but when I go to a haunted house, I expect to see a few real people! I saw 3 live humans the entire walk through. Hello?!? That is incredibly not scary!
