Pretty Little Liars

We're not sure exactly what to expect from this new ABC Family show as the description we read makes it sounds like a teen slasher film.  Here, we'll tell you about it and then you tell us what you think (just make sure to say the description in a deep and mysterious voice).  One year ago there were five friends, best buds forever... until one of them - their leader - went missing.  The four remaining girls swore an oath never to tell what happened.  But, when they start receiving mysterious letters with information only their friend would know, everything changes.  That's just about when the slasher guy usually shows in the previews, isn't it?
