Homer's behavior has changed a number of times through the run of the series. He was originally "very angry" and oppressive toward Bart, but these characteristics were toned down somewhat as his persona was further explored. In early seasons, Homer appeared concerned that his family was going to make him look bad; however, in later episodes he was less anxious about how he was perceived by others. In the first several years, Homer was often portrayed as dumb yet well-meaning, but during Mike Scully's tenure as executive producer (seasons nine, 1997 to twelve, 2001), he became more of "a boorish, self-aggrandizing oaf". Chris Suellentrop of "Slate" wrote, "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." Fans have dubbed this incarnation of the character "Jerkass Homer". At voice recording sessions, Castellaneta has rejected material written in the script that portrayed Homer as being too mean. He believes that Homer is "boorish and unthinking, but he'd never be mean on purpose." When editing "The Simpsons Movie", several scenes were changed to make Homer more sympathetic.
