Again: It's an interactive attraction and you are not fairly reviewing the interactivity by watching a video of it.
The reason these rides work, and keep getting added to parks, is that they encourage communication and dialogue between members of a family or party in a way that is mostly lacking in the modern world. They are providing family entertainment.
Watching a video on YouTube and then complaining that the sets don't look right, the video looks cheap, the music sounds off, or that it just looks boring, missing the entire point of the attraction. You'd be better off reviewing a movie you hadn't seen.
Wouldn't you have to be in the Twilight Zone the entire time, in order to believe that this hotel, abandoned for years, is still powered up and playing music?
