"Shock Labyrinth" really only has it's boffo title and packaging going for it. Everything else about the movie fails to deliver.
The plot...well, apparently a group of friends visit a spooky fairground attraction as children and there is some kind of accident in which one of the girls vanishes. Then, 10 or so years later the same friends find themselves tricked into going to an abandoned hospital, which then turns into the same funhouse from their past, and they re-live the frightening experience all over again, possibly as part of the twisted revenge of the missing/dead girl.
That might have worked as a plot, in fact on paper it looks pretty good, but watching this movie is absolutely no fun at all. There is but a single key event in the movie, which is that somebody falls over the handrail and down the well of a spiral staircase. Believe it or not, the whole film is constructed to dwell on this one event in as many ways as it is possible. First we see the original accident, then we see it again from another view, then we see other characters go through the same event either as witnesses or as victims themselves, sometimes in their childhood and sometimes in their adult states. The film thinks it's clever in mixing the evens of the past with the present, but it doesn't hold any suspense whatsoever, it just looks like a bunch of kids running in circles and then a bunch of adults running in circles again. The so-called shocks of the labyrinth are provided by (wait for it) a white toy bunny and a yellow balloon with a smiling bumble bee on it. Shots of the bunny in particular are wheeled out interminably, not that a single shot of it provokes any feelings of fear whatsoever. At no point in the film does anything approaching scary happen. Not in one single minute of it, and therefore I count "Shock Labyrinth" as a total failure to entertain.
By the way, the DVD comes with both 3D and 2D versions, and if they think the 3D will rescue it, think again. It's totally unwatchable, I only lasted about 1.5 minutes before yanking off the 3D specs and sticking the 2D version on
