I just got the DVD from DVDShelf (or whatever it's called now). It comes with 1 pair of red/blue 3-D glasses. The 3-D scenes are only about 15 minutes total. A little 3-D icon appears in the upper left hand corner of the screen letting you know that the scenes are coming. Maybe it was just me, but I thought the 3-D effects were a blurry mess.
I had read a couple bad reviews, but the idea of a haunted amusement park appealed to me. Unfortunately, the movie wasn't scary and the sets were unimpressive.
Overall, it was pretty disappointing.
Speedy thing goes in. Speedy thing comes out.
