When you have a 40 minute mystery that delves into a million different possibilities, you basically have a mess. What started as suicide, leads to love and betrayal, to demonic possession, to conspiracy, to prescription drugs and finally back to love and betrayal. In this hoopla of things, we clearly forget the fact that Shawn pretends to use his psychic powers to solve a case. We did miss all the zoom-into objects, things appearing through a filter and a blur, and the kkszzzhhhichh sound.
The usual Exorcist, or Emily Rose spoofs and the forced humor like the priest opening his exorcism with joke, or Frank playing with his Xbox were a touch overdone. This and the previous installments clearly show, Psych is veering in some arbitrary direction. Bring the old Psych back.
