Psych is an all-around great show - the cast, the characters, the acting, the directing - but Season 4 was a fantastic season. As you get to see more about the relationships between the characters and they show you a bit more about how they all interact, it just gets better and better. The finale was hands-down the most amazing episode (stellar job directing, James Roday!), but some other favorites from the season are: Thrill Seekers and Hell Raisers (one of my all-time favorites), Death is in the Air, A Very Juliet Episode, High-Top Fade Out and The Devil's in the Details...and in the Upstairs Bedroom. I can't say enough about this show and I will be a fan for life. If you like a little bit of drama mixed with a hearty dose of humor and 80s references, you will love this show. I definitely recommend it!
