Pretty Little Liars is one of the most literature allusion-laden shows on TV right now, and much like Lost before it, the references serve to enhance the show's central mystery plot line. There is no point in my trying to summarize what is going in in this show because its fifth season premiered last week and it is already so far down a ridiculous path that I wouldn't know where to begin, so I'll just say that it's the high school version of a "dead girl" show, and unlike its natural predecessors like Veronica Mars or Twin Peaks, it does not get bogged down by the central murder story in the slightest. It is extraordinarily campy, but also completely self-aware, and is just the best thing ever.
