Every Season Of Psych Ranked Worst To Best

Running for eight seasons and three television movies, the USA Network's popular crime comedy series "Psych" debuted in 2006 and put the fun back in murder mysteries. The series follows private investigator Shawn Spencer (James Roday Rodriguez) and his lifelong best friend, Burton "Gus" Guster (Dulé Hill), as they work with the Santa Barbara Police Department to solve tricky crimes. In a premise similar to "The Mentalist" (but predating that CBS procedural by two years), Shawn is brought in due to his purported psychic abilities. However, his keen observational skills fuel his crimefighting.

More than just a standard crime show, "Psych" leans into the comedic chemistry between its ensemble cast, buoyed by an extensive roster of guest stars each season to join in on Shawn and Gus' irreverent antics. As the series progresses, "Psych" incorporates more overt pop culture references, from parodies of popular films to an entire musical episode. Here are all eight seasons of "Psych" ranked from worst to best.

As funny as the writing and performances in "Psych" are, there is a definite formula behind many of the episodes. That is especially apparent towards the end of its run. The penultimate season of "Psych" is when the storytelling formula finally wears a bit too thin, even with its attempts to shake things up. The biggest development is Juliet O'Hara (Maggie Lawson) learning Shawn has been lying about being a psychic all along, leading to a temporary breakup.

Juliet and Shawn's romantic rupture highlights the show's struggle to find new directions seven seasons in, with Shawn and Juliet reconciling quickly, leaving the audience to wonder why such a fuss was made about the breakup at all. There are bright spots in the seventh season, to be sure, including guest star appearances by Christopher Lloyd and Cybill Shepherd's return as Shawn's mother, Madeleine. But with the tropes becoming increasingly derivative and with even more forced drama in the finale as the police department is taken over by the no-nonsense Harris Trout (Anthony Michael Hall), the show is running on fumes.

Clocking in at 10 episodes, the eighth season is the show's shortest, but this truncated episode order ultimately works to the series' advantage. The final season of "Psych" brings in plenty of familiar faces from seasons past and, as only a show as self-aware as "Psych" can, remakes an episode from the first season. The narrative formula still feels worn at times, but the eighth season lays the groundwork for the eventual series finale, restoring the status quo briefly before longtime characters depart from Santa Barbara.

The most interesting addition to the show in its final season is new head detective Betsy Brannigan (Mira Sorvino), who plays well off both Shawn and Carlton Lassiter (Timothy Omundson). Each of the main characters gets their moments to shine, giving the show the happy ending it deserves. "Psych" may have noticeably grown a bit long in the tooth by the end, but with a solid back half to its final season and series finale, it sticks the landing.

As with most shows, "Psych" came out the gate trying to find its voice and overarching tone. This is apparent from the pilot episode, with a relatively more serious Shawn; a deeper estrangement between Shawn and his father, Henry (Corbin Bernsen); and Shawn being less noble than who he quickly transformed into. The murders that Shawn and Gus investigate (including a serial killer targeting a sorority house "Black Christmas"-style), while not overly macabre, are generally darker than those in subsequent seasons. 

Most significantly, the fan-favorite character dynamics that would elevate "Psych" haven't fully gelled in the inaugural season as the show figures out how to best deploy its cast. Beyond the more contentious dynamic between Shawn and Henry, Shawn hasn't quite warmed up to Lassiter or Police Chief Karen Vick (Kirsten Nelson). It is fascinating to watch how quickly the show pivots and lightens its tone as the first season progresses, but there is still tonal whiplash when revisiting the early episodes.

By the second season, "Psych" has largely found its narrative, though there still is the underlying lingering feeling, at least early on, that some of those growing pains are still present. Shawn and Gus' freewheeling approach to solving crime is set, while Shawn and Juliet really lean into the flirtatious rapport that helps power the show. Shawn and Henry's father-son relationship similarly finds its proper balance, though Shawn's stance with the Santa Barbara police, specifically Lassiter, is still tenuously being established.

The biggest boon that the second season boasts is having guest stars Tim Curry and Gina Gershon in the season premiere, poking fun at musical reality shows like "American Idol." As "Psych" progresses, it features an impressive line of guest stars playing off Shawn and Gus, and the season premiere sets the template for this moving forward. A significant improvement over the first season, "Psych" truly comes into its own, though it's still not quite firing on all cylinders.

As "Psych" hit its stride, the series increased the frequency and profile of its guest stars. This became noticeable by its fourth season, which boasted the likes of John Cena, Jeri Ryan, and Kenan Thompson. However, along with one-off guest stars, the fourth season introduces several fan-favorite recurring characters who help elevate the latter half of "Psych."

The charming art thief, Pierre Desperaux (Cary Elwes), has his first confrontation with Shawn and Gus in the fifth season while the Santa Barbara Police Department gains the hilariously macabre coroner, Woody (Kurt Fuller). The recurring character the season uses most effectively is Abigail Lytar (Rachael Leigh Cook), who strikes up a romance with Shawn across a four-episode arc. Shawn and Abigail's relationship was always destined to fail, but it would give "Psych" the final push to help Juliet realize her true feelings for Shawn, even if their romance takes longer to begin.

After nearly five seasons of maintaining a flirtatious dynamic, Shawn and Juliet finally take their relationship to the next level — after Juliet briefly dates a local criminal profiler (Nestor Carbonell). Beyond a longstanding promise of romance finally being fulfilled, the fifth season of "Psych" offers plenty of great moments that elevate it considerably. Season 5 features a parody of "Twin Peaks." That alone propels it into the series' top three seasons, but most importantly, it ends with one of its strongest finales.

Ever since the third season, Shawn and Gus have faced off against the cunning serial killer, Mister Yang (Ally Sheedy), who takes a particularly unhealthy interest in Shawn. After resurfacing in the fourth season, Yang returns in the fifth season finale along with her father, Mister Yin (Peter Weller). This showdown, along with guest stars like Ralph Macchio and Carl Weathers earlier in the season, brings the fifth season to lofty heights as "Psych" continues to deliver.

The sixth season of "Psych" is the last to thrive on the show's underlying formula and a bevy of overt pop culture references and guest stars. Shawn and Juliet are thriving as a blossoming couple. This leads to the introduction of Juliet's father, Frank (William Shatner), who plays a recurring role in the season. Coming out the gate with a guest appearance from Malcolm McDowell, the season ends on one of the series' best cliffhangers, as Henry is shot in the chest, leaving the audience to ponder his fate.

The sixth season is "Psych" making the best use of its creative excesses before the gradual decline that began with the subsequent season. The pop culture riffs, including send-ups of "Indiana Jones" and "The Shining," work without coming off as tired and forced as in the last two seasons. Though this season tends to veer into self-indulgence, the formula hasn't yet overstayed its welcome.

By its third season, "Psych" emerges from any growing pains it had at launch and settles into the style and tone that serves it well for the remainder of its run. This season marks the introduction of three recurring characters who help shape the trajectory of future seasons: Abigail Lytar, Mister Yang, and rival detective Mary Lightly (Jimmi Simpson). Quickly becoming fan favorites, each of these characters assists or menaces Shawn and Gus moving forward. However, there is something about each of these characters' respective debuts that stand out as memorable.

The third season also marks the last in which the cavalcade of guest stars doesn't seem like an overdone gimmick. The guest appearances are more organically integrated into the story, favoring character over an actor's profile. Far from the knowing self-parody "Psych" would settle into in its later seasons, the third season sees the show confidently embrace its quirky voice while mixing comedy with crime thrills.
