I don't know what it is about corn mazes that makes them so creepy, but they are. I say that with no personal experience whatsoever, as (sadly!) I've never been in one. They do seem to turn up fairly often in horror, however, so it seems like there's lots of people who find them as appealingly creepy as I do. This likeable story, about a couple stopping for a break on a long car trip, is not exactly surprising - you know the maze, or something in it, is going to get them, just as you know that people who decide to spend the night in a haunted house will come to sincerely regret it - but even so there's a nice sense of claustrophobia here. And I did enjoy the spiders...
