One of the two narrators has a voice that will put you in a perpetual cringe. He seems to be impersonating a woman trying to sound like a guy but instead produces a fingernail across a chalkboard voice that seems to be on the constant verge of letting loose with a humungous belch. It’s an alien sound — no human male sounds like this — that would not be out of place in a sci-fi B-movie sound effects repertoire but here ruins what is otherwise an OK, even somewhat decent story.
