I saw the movie, and aside from not being new, it's dreadful, and I don't recommend it to anyone above the age of 15 in this forum.
It's basically if R.L. Stein, writer of "Goosebumps", threw the "Spy Kids" family into an episode of the "X Files" which took place on the set of "Degrassi Jr. High", and threw in that weird pagan cult from "Dragnet". Costumes and all.
For fun, they had it star the Noxzema girl, who ended up having an inter-racial relationship for no reason?
Steer clear of this one, unless you liked that Nickelodeon show about being afraid of the dark.
