Mike Scully, who was showrunner during seasons nine through twelve, is held responsible by many critics and fans for the decline. An op-ed in "Slate" by Chris Suellentrop argued that "The Simpsons" changed from a realistic show about family life into a typical cartoon when Scully was the show runner: "under Scully's tenure, "The Simpsons" became, well, a cartoon. Episodes that once would have ended with Homer and Marge bicycling into the sunset now end with Homer blowing a tranquilizer dart into Marge's neck. The show's still funny, but it hasn't been touching in years." John Ortved wrote in his book "" that "Scully's episodes excel when compared to what "The Simpsons" airs nowadays, but he was the man at the helm when the ship turned towards the iceberg." "The Simpsons" under Scully has been negatively labeled as a "gag-heavy, Homer-centric incarnation" by Jon Bonné of MSNBC, and many fans have bemoaned the transformation in Homer's character during the era, from sweet and sincere to "a boorish, self-aggrandizing oaf", dubbing him "Jerkass Homer".
