First, let me say that I love Psych and James Roday. I love John Landis. I, however, hated this episode. It made no sense at all.
The setup was good. The bride gets a note that she is marrying a serial killer. Okay, I buy that. They had not known each other long. She had bad luck in relationships.
Then the whole show dissolved into the bride blindly running around alone. Where was the maid of honor? She met the out-of-nowhere twin uncles. Who cares? The groom runs after her, and she is terrified. Why?
I am all for red herrings and twists, as long as they make sense and are well done. The red herrings went nowher. The twist negated everything we had seen in the entire episode. What a cheat!
