Community creator Dan Harmon is not happy with how season 4 of the show went, unleashing a rant on his Harmontown podcast on Monday.

Harmon, who was famously fired from Community by NBC after season 3, announced on June 1 that he would be returning to the show for its upcoming fifth season. He told listeners of his Harmontown podcast that he just recently finished watching season 4 of the show, which was produced under the control of new showrunners David Guarascio and Moses Port.  To say that Harmon was not pleased with the final product is an understatement.

"Man, watching those characters without me there is just not f--kin' cool, man," he said in reference to the fourth season, "It's like flipping through Instagram and watching your girlfriend just blow a million [other guys]."

On Guarascio and Port, Harmon asserted that they had no idea what they were getting into: "They went to Comic-Con, saw what was going on ... and they went 'F-ck.' They tried their best."

In particular, Harmon hated the casting of Jeff Winger's father, who he always envisioned to be Bill Murray. Instead, James Brolin was brought in for season 4 to play Jeff's father.

"There's something awesome about having all of those preconceived notions ripped away from you," he said, bitingly, "It's exciting. There's something exciting about being held down and watching your family get raped on a beach. It's liberating. It makes you focus on what's important." 

Harmon had previously said that he was going to watch season 4 and voice his opinions but he was "not going to be a jerk about it."  He mentioned that there were still writers on the fourth season that were there from the beginning of the show, so it would be wrong to "fart in their direction at all."

Though his comments on his podcast seem harsh, he did also say that Guarascio and Port "accidentally created a TV show with a bunch of great actors that makes people really happy, and now we have 13 more episodes."

Community's fifth season will air at some point on NBC in the 2013-2014 season, though there is no scheduled airdate.
