The horror genre loses another plot device

You know how thrillers have had to adapt with the advent of the cell phone? It used to be you could put your protagonists on a train or a remote mountain and their communications would be gone. Now, you have to either have everyone getting no signal (which gets less and less believable as time goes on) or everyone out of battery power (which might work for a cast of one or two, but if you have an ensemble of five, not so much).

Not that this is a super-popular device, but Scary Go 'Round gives us a traditional setup: two teenaged girls and a vaguely occult, supposedly unsolveable maze. Of course the girls will go in. Of course we expect them to get lost.

Ester's more clever than that.
