I have been a fan of Psych since the show debuted, but I was starting to notice a trend of general silliness and repetitiveness. The past few shows have shown a new depth to the characters of Shawn, Lassiter, and (sorry, forgetting Corbin Bernstein's character name) Shawn's dad. Instead of Shawn catching everything right away and making everyone else look like the goofy sidekick, Gus is now catching some things that Shawn is missing. Instead of always getting the girl, Shawn is willing to step back (and even sabotage himself) and let Gus go at it. The relationship between Shawn and his dad is starting to become something interesting in itself, and the interaction and love/hate relationship between Shawn and "Lassie" is excellent.
The obligatory silliness is still in there (I nearly fell over when the judge was pointing at the attorney with a stalk of asparagus) and helps make the show what it is. The extra dimensions that are being added to both the characters and to the plots are going to be what keeps this show around for several years (I hope).
Anyway, this past show, in my opinion, has been the best thusfar, but they have been getting better and better with each new show this season. Kudos to the writers!
Now, can we please keep the "Psych-Outs" to just Roday and Hill?
