It must be incredibly difficult to create a creative and genuinely scary haunted house tailored to all ages. The reason I say that is because so far I have not found one, and 13th floor is no exception. However, compared to all of the others this one was pretty good.
The length of the attraction was great, and the sets were very good too. The actors were fine, I just feel like they are all very predictable. I can usually tell where the jump scares are (especially because my group made me go first) and having someone run at me is not very scary when I know it isn't real.
I would be interested to check out the black-out night. That might up the intensity enough to differentiate the 13th floor from other run-of-the-mill haunted houses. If I end up going I will update the review!
