Mind you I'm not a big Psych fan per say but as far as this episode goes they really knocked it out of the park. For starters they totally nailed the whole Twin Peaks thing. From the plot, to the creepy music, the obsession with donuts and pies, the weird, over the top dramatics (I remember how weirded out I was back in the day from all the insane crying they did in Twin Peaks) and I laughed my head off when they made fun of that in this episode. Bringing back all those old school Twin Peaks actors was just awesome. There was a nuance from that show in every scene. The downside? Well if you've never seen Twin Peaks none of this will make sense and you'll have missed all this cool stuff ;) Without prior knowledge of Twin Peaks this episode will probably come off as strange and disjointed. Outside of that it's still good, the usual result from any given Psych episode (as I said, not a huge fan of the show)
