Merry day after Christmas! I completely forgot about reviewing Psych until Friday, so here's some brief thoughts on the season finale.
"Yang 3 in 2D" wraps up the Yin-Yang saga in similar fashion to the previous two Yang episodes. It's much more serious than usual with lots of tense moments and not the goofy humor we usually see. We learn the origins of the killers and Yin, played by Peter Weller, is the ultimate villain, not Yang who was more of a pawn. The family drama of the crazies reflects on Shawn's own family which is less dysfunctional in comparison. All in all, it's a solid ending to plot which began in season three.
Score: 8.9/10
