TNT's has cancelled drama series Perception after three seasons. The show is the latest victim in Kelly Reilly's brand evolution of the channel, with Franklin & Bash also getting culled earlier this year.

Perception starred Will & Grace actor Eric McCormack as a talented but eccentric neuropsychiatrist hired by the FBI to assist in solving some of the most complex cases in Chicago. It was popular with viewers and although the third season was down 9% on season two, it still drew a very solid 2.8 million viewers. Perception opened its fourth season with 3.1 million viewers - a huge increase on the recent Franklin & Bash opener, which pulled in just 1.25 million.

Nevertheless, Reilly is committed to providing edgier, more original fare on TNT and both Franklin & Bash and Perception were shipped in from outside studios. 

"We are going to get edgier, we are going to get louder, and we are going to get more dual (male-female), but we also have an existing audience, we have an existing fan base with a lot of our very popular shows," Turner Broadcasting's David Levy said this month. "It's an evolution, a bridge-type process that will take place as opposed to a turnaround."

"A sad day: Daniel Pierce will lecture no more. Thank you #Perception fans, and our great crew, for 3 amazing seasons. Shoulda been more..." McCormack tweeted on Thursday after hearing the news.

His co-star Rachael Leigh Cook said: "Solving 40+ (fictional) federal crimes ain't bad. HUGE thank you to everyone who tuned in to @PerceptionTNT it was a truly great experience."

Debra Messing, McCormack's co-star on Will & Grace, tweeted her congratulations to McCormack and Cook, saying, "CONGRATULATIONS on an amazing show!"
